NEW!! Synful Orchestra 2.5 New French Horn 

What's New in 2.5.x - The New French Horn

  • Listen to the new horn sound examples
  • Using the New Horn Instructions
  • The first fully expressive instrument to use our new synthesis engine.
  • Uses all new sample recordings.
  • Continuous control of timbre from darkest to most brassy.
  • Natural phrasing using only note-on/note-off and velocity.
  • No Delay for Expression for the new French Horn.
  • Dynamic gliss and rip effects with complete control of gliss rate.
  • Open sound, two different mutes, stopped sound.
  • Continuous Wah control for mute and stopped sounds.
  • Continuous Trill control.
  • See the horndemo example projects and midi file.
  • Read More about the New Horn


  • MIDI “All Notes off Message” now works.
  • Fixed bug causing Synful Orchestra to crash under Windows Finale.
  • Fixed problem with Authorization panel not appearing on some Windows machines.

What’s New in 2.5.5

  • Added support for Max OSX 10.7 Lion

What’s New in 2.5.2

  • Fixed a bug that can cause notes to dropout when playing with DFE in some situations.

What’s New in 2.5.1

IMPORTANT NOTE: the new vibrato depth control for the horn is mapped to the Mod Wheel (cc1) by default. If you have mapped the mod wheel to anything else – e.g. gliss rip control – in any project which uses the new French Horn, then you may want to remap the control or turn the vibrato depth/mod wheel mapping off.

  • Added vibrato depth control to the new French Horn. The trill control has been moved to the place of the wah control and the harms tilt slider becomes the wah control when a mute or stopped Playing Mode is selected.
  • Added the ability to change banks without sending a new MIDI program change message. This means you can, for example, create a “pizz” symbol in Finale or Sibelius which just sends a bank change and will work for all the string programs. See the updated section Control Parameters in Programs and Playing Modes in the Help or users guide for details.
  • Made MIDI program 127 a “no change” program. If you make a bank change and then send a MIDI program change 127 the program will remain unchanged but the bank will change. Also good for creating “pizz” etc. symbols in Finale and Sibelius.
  • Fixed a bug that caused some short notes to have abnormally abrupt releases.
  • Rebalanced some notes that did not have even loudness.
  • Updated horndemo files so that Mozart example plays in the correct key of Eb -- not Bb as before.

What’s New in 2.4.x

IMPORTANT: If you are a Windows user you must reauthorize – see below.

Be sure to read the section Upgrading to 2.4 in the Help for full details on these new features:

  • Full String Playing Modes. pizzicato, bartok-pizz, col-legno, tremolo, harmonics, sul-ponticello, sul-ponticello-tremolo.
  • New Powerful Controls. Adjusting harmonic tilt, release time, and release noise level in pizzicato strings creates all kinds of Koto, African Kora, and otherworldly sounds. You can adjust tremolo speed from almost a dead stop to inhumanly fast without altering fidelity of the original recording. The bow noise control continuously adjusts a string tremolo from sharp and jagged to a smeared out shimmer. The new sforzando control continuously stretches and emphasizes the first strokes of a tremolo just like a real player.
  • New Synthesis Engine. Achieving hi-fidelity in a sampler is easy when you're just playing back digital recordings. But if you want to stretch and compress the durations of sounds, alter characteristics like bow and breath noise, adjust the levels of individual harmonics in the sounds, and splice sounds together in complex ways, then preserving the fidelity of the of the original recording is much more difficult. We believe we have achieved this with our new synthesis engine. The new string playing modes are the first to use our new synthesis engine, preserving full 24 bit fidelity while allowing us the flexible morphing capabilities we need for Reconstructive Phrase Modeling (RPM) – see www.synful.com/RPM.htm.
  • Protools/RTAS Compatibility (Mac Only). Finally Synful Orchestra runs under Digidesign Protools software. This is for Mac only for the time being. We will have a later release that support Protools on Windows machines.
  • Sibelius 5 Direct Plugin Compatibility. We have received so many requests! Earlier this year Sibelius 5 was introduced, featuring full plugin in host features for AU and VST plugins. Use either format on Macs and PCs and combine the expressive power of Synful Orchestra with the powerful notation and sequencing capabilities of Sibelius.
  • Keyswitching. To access the new playing modes you can use keyswitching, MIDI program changes, or the Control Panel. Articulations that normally occur in arco string playing such as spicatto, detaché, normal legato, bow-changes, attacks of various kinds, etc. are still automatically selected based on normal Midi input. However Playing Mode changes from arco, to pizz, sul-pont, etc. are choices that the composer/performer must make and keyswitching makes these very convenient.
  • Flexible MIDI Controller mapping. You can now map any MIDI continuous control to any Synful Orchestra parameter. No more Volume Only or Volume and Expression switches.
  • Small Size. Uses 120M of memory – no disk streaming.
  • Flexible Control Parameter Names. The name of Control Parameters may now change depending on the Program and Playing Mode and are more appropriate to the instrument. For example, the old “sustain noise trim” is now called “breath noise” in flute and “bow noise” in strings. See Help for full details or just play with the Control Panel.
  • Simpler and More Flexible Program Management. See the Help for details about Local Channel Programs, Save Load Default Programs, Renaming Programs, etc.
  • Pre 2 .4 Mode. A number of things have changed in version 2.4.x but we want to make sure your old projects load and sound the same. For the most part this happens automatically however there is a new button called Pre 2.4 mode on the Control Panel which is on by default when you open an older project. 99% of the time you can and should turn it off. See the Help section on Upgrading to 2.4 for full details.
  • Changed MIDI Program Number . It used to be that we displayed MIDI program or patch numbers from 1-128. Now we display them from 0-127. This will not affect your sequences or projects. It is just how we display the numbers in the Program and Playing Mode pop-up lists. So where Violin used to be displayed as MIDI Program (or patch) 41, now it is displayed as 40. The reason for the change is that most controllers and sequencers seem to do it this way (however, the fact remains that they do not all agree!).
  • Integrated Authorization. On Mac there is no more SynfulOrchestraAuthorizer – just a button on the Control Panel. Authorization and trial period status is displayed on the Control Panel.
  • Windows Machines Require Reauthorization. We have changed the copy protection scheme on Windows to be the same as Mac. See Purchasing and Authorizing in the Help for instructions.
  • Windows Vista, XP64 and Vista64 Compatible.
  • Mac Universal Binary, Leopard Compatible
  • Logic 7/8, Cubase 3/4, DP5, Sonar 6/7, Live, Garage Band and Many more
  • Logic 8, Cubase 4, DP5 Compatible
  • Many Bug Fixes.
    • Switching Programs and Playing Modes while playing live or in the middle of sequences is now much more reliable.
    • Fixed problems in time-spread control over sections.
    • Fixed problem with Pitch Bend control being undelayed under certain circumstances when Delay for Expression is on.
    • Many more
    • See below for bug fixes in 2.4.1 for 2.4.0 beta

What’s New in 2.4.4

  • Fixed an important bug that occasionally caused users to lose their Synful Orchestra Control Panel setups when they saved a project file.
  • Fixed a problem that sometimes caused the challenge/response authorization window to freeze up so that it was not possible to paste in a response code.

What’s New in 2.4.3

  • Protools/RTAS Compatibility (Mac Only)
  • Fixed memory consumption problem that caused sluggish behavior, and even occasional crashes, especially with Logic projects that include many instances of Synful Orchestra.
  • Fixed problem with intonation of high notes in tremolo, sul-pont, and sul-pont-tremolo playing modes.
  • Fixed problem with enabling, saving and restoring MIDI CC control assignments – this problem only occurred under some unusual circumstances.
  • Fixed problem with assigning MIDI CC automatically when loading pre 2.4 projects.
  • Fixed a problem that could cause random crashes do to improper handling of note-on events with pitch slide.
  • Fixed a problem which, under some conditions, caused the New Authorization window to come up even when Synful Orchestra was already authorized.
  • Protected against reading in of project files containing corrupted Synful Orchestra AU preset data

What’s New in 2.4.2 - Bug Fixes

  • Fixed Channel Pressure and Key After Touch MIDI controls. These did not function at all prior to 2.4.2.
  • Fixed MIDI program/patch numbers for the Violins1, Violins2, Violas, Cellos, Basses programs. The alternate playing mode program/patch numbers for these programs were set to the same thing as the solo instruments Violin, Viola, Cello, and Bass. This made it impossible, for example, to save a project with Violins1, Violins2, Violas, Cellos, Basses selected because they would always be read back as the solo instrument programs. In addition Cellos arco was set incorrectly to bank 0 and has now been corrected to be bank 1. NOTE: if you have sequences with embedded program changes for Violins1, Violins2, Violas, Cellos, Basses that use the alternate playing modes you may need to correct the program/bank numbers for these sequences.

What’s New in 2.4.1 - Bug Fixes from 2.4.0 beta

Version 2.4.1 is the first non-beta release for 2.4.x. Version 2.4.1 fixes a number of bugs associated with the beta version 2.4.0. Version 2.4.1 introduces no new features that were not in 2.4.0.

Bug fixes in 2.4.1:

  • Fixed a bug that caused Synful Orchestra and the host sequencer to crash when scrubbing tracks by dragging the location button in DP and other sequencers.
  • Fixed a significant bug in loading existing (pre 2.4.x) projects and templates that include Synful Orchestra. This bug was capable of causing a wide variety of irratic behavior – host sequencer crashes, random values in controls, interference with other plugins, etc.
  • Fixed a bug that caused slow degradation in performance over time until 100% of CPU was used – noticeable if looping for a long time (e.g. 10 minutes to 1 hour).
  • Fixed a bug that created erratic unpredictable behavior in saving and loading new programs. This would not cause a crash but would appear as random parameters not being saved or loaded with the project.
  • Fixed a problem that would sometimes cause Synful Orchestra to be unrecognized by the host sequencer.
  • Fixed problem with blank/white feature list during Windows 64 bit install and inability to complete install.
  • Fixed problem with installaion of 64 bit Windows drivers.  

What’s New in 2.3.2

This is a new Mac Universal Binary version of Synful Orchestra 2.3.2. It runs on both new Intel Macs and older Power PC macs. This version has no new sounds or other new features compared to version 2.3.0. So the only reason to download and install this is if you want to run Synful Orchestra on a new Intel Mac. There is no version 2.3.2 for Windows. The latest version for Windows is 2.3.1.

What’s New in 2.3.1

In 2.3.1 we have fixed a bug in the DXi version of Synful Orchestra 2.3.0. This bug affects users of Sonar on Windows or other users of the DXi version of Synful Orchestra. The bug does not affect MAC users or Windows VST users. There is no version 2.3.1 for MAC. The bug introduced unpredictable and variable time delays in output ranging from 0.1 to 1.5 seconds.

What’s New in 2.3.0

  • String Sections. Wind and Brass Sections. Any Synful Orchestra solo instrument can now be turned into a natural sounding section. Synful Orchestra uses the RPM database to guarantee realistic variations between the players. You can select the number of players in the section, how the players are positioned on stage, the rhythmic variation between the players, detuning among the players, and more. Listen to the new Tristan und Isolde example included in the download to hear the naturalness of these sections. See the Synful Orchestra help section on Localization and Section Controls for full details about sections.
  • Natural Divisi. Synful Orchestra sections simulate realistic and natural divisi. For example, if you create a ten violin section Program and play a monophonic line then all ten players will play that line. If you play a ten note chord then each player will play one note in the chord. The Synful Orchestra section automatically adapts to the changing polyphony of the part. If you play 3 note chords or polyphony then the ten players distribute themselves automatically 4-3-3 across the notes.
  • Player Position. Synful Orchestra virtual players can be positioned in the listening room. The position of the virtual listener can be changed and the room size can be adjusted. The new ability to create sections uses the positioning capability to make the different players in a section sound like they are spread out realistically in space. See the Synful Orchestra help section on Localization and Section Controls for full details about sections. IMPORTANT NOTE FOR LOGIC USERS: If you use Apple Logic and want to use the Synful Orchestra direct, 2 walls, or 4 walls localization controls then you must set the MIDI pan in Logic to the center or to off. This is because Logic performs panning itself which will interfere with the more powerful Synful localization modes.
  • Bigger and Prettier User Interface. We have added a number of controls to the Control Panel to support player localization and sections. We have also upgraded the look a bit so it’s prettier and more consistent (we hope!).
  • Degradation Over Time Bug. We fixed a problem which caused Synful Orchestra to have reduced performance over time. So if you ran for 1-2 hours you might have to stop Synful Orchestra and the host sequencer and restart them to get rid of clicks and pops that had emerged. This was quite apparent when using Cubase on PC/Windows but it was true to some extent on every platform.
  • Better Performance. We have improved the efficiency of Synful Orchestra so you now get more voices on the same computer.
  • Better Note Transition Modeling. We now take better advantage of Delay for Expression for modeling note transitions, especially in advance of an upcoming note.
  • New Orchestral Example. We have included a new MIDI example of an excerpt from Wagner’s famous Prelude to Tristan und Isolde to demonstrate string and wind sections and the ability to model the entire orchestra.
  • Program Locking. There is now a button associated with every MIDI channel on the Control Panel that locks the Program assignment for that MIDI channel so that changes coming from a MIDI controller or from the host sequencer do not override the Program setting in the settings in the Control Panel.
  • Enter Control Values By Typing. You can now enter control values in the Control Panel by typing in the numerical display boxes in addition to adjusting the slider or knob positions.

What's New in Older Versions of Synful Orchestra

Free Crossgrade for Windows and Mac

If you already own Synful Orchestra or if you purchase a new license you can use it on both your Mac and Windows machines. See Free Crossgrade.

Wagner, Beethoven and Stravinsky Examples

One of the best ways to learn Synful Orchestra is to examine the examples included with the installation. There are examples from several composers including a Beethoven String Quartet, Stravinsky Rite of Spring, and Wagner Tristan und Isolde.


  • Mac OSX. Go to Macintosh HD/Applications/Synful/Synful Orchestra/Examples. .lso is for Apple Logic, .dpf files are Digital Performer, cpr for Cubase, and .mid for simple Midi.
  • Windows. Go to /Program Files/Synful/Synful Orchestra/Examples. .cpr is for Cubase, .cwp for Sonar, and .mid for simple Midi.

Sequencers We Test With

We currently test Synful Orchestra with Apple Logic, Digital Performer, Cubase SX, and Sonar. There are known problems with some other sequencers that we do not currently test with -- see KnownProblems.htm. Generally if Synful Orchestra works with one product from a company it will work with others. For example Nuendo, Cubase SL, and V-stack all work well since Cubase SX works well. For products we do not test with, we cannot guarantee correct behavior. It is also possible that for products we do not test with Synful Orchestra will work now but not work after either we or the sequencer company releases a software update. We will try to fix these problems if they occur but this may take time. We will gradually expand the number of products we test with over time. We apologize for any problems this causes.

Known Problems With Synful Orchestra

Synful Orchestra Needs a Host Sequencer Program

Synful Orchestra is a plugin program that cannot run by itself. It needs to run with a host program. It supports three plugin formats AU, DXi, and VST. AU and VST run on MAC. DXi and VST run on Windows. There are many AU, DXi, and VST host programs including some free ones. If you do not have a VST or DXi host program you can download a free trial of these popular DXi and VST programs:

Download Demo Version of Sonar DXi Host Program from Cakewalk (Windows)

Download Demo Version of Cubase VST Host Program from Steinberg (Windows and Mac)

Activating or Authorizing Multiple Machines. Upgrading Machines

If you have purchased a Synful Orchestra license and received an Activation Code then you can authorize Synful Orchestra on more than one personal machine. For example, a desktop and a laptop or a PC and a MAC. The Synful Orchestra license is considered to be for one person. However, we will support as many machines as you have within reason. 2-3 is normal, 10 is way too many! Do not share your Activation Code with friends or colleagues. It identifies you as the only person who can receive authorizations for your personal Synful Orchestra License.  If you use Automatic Internet activation then after 3 activations you may need to contact Synful Orchestra by email at support@synful.com to request further activations.

Certain kinds of hardware upgrades and sometimes reformatting of the hard disk will require a re-authorization. Simple follow the steps described in the previous section to re-authorize.
