This release contains fixes for serious bugs that were unfortunately found after version 1.10 shipped. It is primarily a bug fix release and not intended to introduce new features, though a few new items have found their way into this code.

The following information describes the changes in this code since the last customer release of Proteus 2000 code, Version 1.10.

• Filter resources used for 12th order filters are now being freed correctly. This caused the most serious of problems, most noticeably causing voices to intermittently not sound at all. If the voice was stereo or chorused this could sound like hard panning, since only one channel of the pair was audible.
• Editing Preset Patchcords when the preset being edited is on MIDI Channels other than the Basic Channel are now refreshed at the time of the edit and use the new Patchcord connections in all referenced instances immediately. Before, a program change was required on any of the other MIDI channels to hear the effect of the edited cord.
• LED indications for I-L knobs now work correctly, again. Cases where the LEDs would not light have been resolved. This bug was originally found in 1.04 code and fixed in 1.05 but was inadvertently omitted from the 1.10 build.
• Saving a MultiSetup no longer throws away all edits in the current preset edit buffer.
• Knob response is greatly improved.
• New Feature - Added a Copy Preset Cords item in the Copy/Save menu. This copies all the preset cord settings from a specified source preset into the current preset edit buffer.

The following information describes the changes in this code since the last customer release of Proteus 2000 code, Version 1.05.

Preset Patchcords, Ramper and Lag Processor
The 1.10 release introduces to the Proteus 2000 user the new Preset Patchcord implementation developed for the B-3 module. This feature includes support for a Preset Level Lag Processor, Ramp Generator and summing cord destinations.

WARNING: Presets created prior to 1.10 that use Preset Patchcords (previously labeled FX PATCHCORDS) assigned to FX Send destinations could have sonic differences if presets have more than one preset cord assigned to an FXSend amount. In previous versions of code, the last cord defined in the patch bay overrode all other cords. Because of this, there was no real reason to use multiple cords, but multiple assignments may have been made unwittingly. Since multiple cords now sum to their destinations, presets could sound different.

NOTE: Existing Editor/Librarians should work fine for storing 1.10 presets, though they may have troubles displaying the new patchcord sources and destinations.

Sound Authoring
This release introduces Sound Authoring to the Proteus 2000 user. This feature allows you to copy a bank of user presets to a Flash SIMM that was created on an E4 Ultra. See the Sound Authoring documentation for a full description of this feature. There are no backwards compatibility issues for existing P2k users with this feature.

12th Order Filters, Dynamic Voice/Filter Allocation
Proteus 1.10 now has the 12th order filters and Dynamic Voice Allocation developed for Audity 2.0. Presets developed with these new filters will not sound the same in pre-1.10 software; unsupported filters play a default null filter. Note that unlike Audity 2.0 where adding DVA potentially increased the polyphony of Audity (when using 6th order filters), in Proteus it can actually decrease the polyphony. Playing a note on a layer that uses a 12th order filter effectively uses 2-6th order voice channels.

MIDI All Notes Off/All Sound Off/Reset All Controllers - The response to these MIDI Mode Messages has changed in OS 1.10 to be compliant with the MIDI 1.0 Spec. In previous versions of software these messages had a number of bugs. Note that these changes could affect compatibility with sequences authored with earlier versions of Proteus software.

In previous versions the software did not honor the MIDI channel of these messages. Instead, it incorrectly affected all channels. It now correctly only affects the notes started on the MIDI channel of the message. If you want All Notes Off on all MIDI channels you must send individual messages for each channel.

In addition, All Notes Off now correctly honors the state of the sustain pedal. It will no longer shut off notes if the sustain pedal is down on its channel at the time of receipt of the mode message. This behavior is especially important to owners of certain keyboards that send All Notes Off whenever all keys are released (i.e. Kawai, Roland).

Also, receipt of All Notes Off now correctly puts the targeted notes into the release phase instead of shutting down the voice immediately.

All Notes Off is basically equivalent to sending Note Off messages on all notes of a particular MIDI channel. This means that if the sustain pedal is held, the notes are not shut down, but remain in the sustain state until the pedal is released. If the sustain pedal is not down, the notes go to the release phase, allowing the volume envelope to control the shutdown of the notes. All Notes Off should not be used as a Panic message to shut down hung notes since notes will not be turned off if the current state of the sustain pedal is down. In addition, the sound will not necessarily stop immediately, since it goes to the release phase, which means the behavior is preset dependent. If you want the sounds to always shut down immediately, you should be using the All Sound Off message instead.

All Sound Off also incorrectly ignored the channel of the message in pre-1.10 software. It now correctly honors the channel. All Sound Off is different from All Notes Off in that it does not look at the state of the sustain pedal, and shuts off the sound of the notes immediately, ignoring the volume envelope. This is the message to use if you want to send a Panic message because notes are hung. Note though that this is still a channel based message, so if you really want ALL sound off for the whole box, you need to send this message on each of the active MIDI channels.

Note that if sequences were written assuming the behavior of the pre-1.10 Proteus 2000 software they will need to be re-worked by the user. There has been no attempt to maintain compatibility, since this is considered a bug in the old implementation.

• The Screen now refreshes correctly after a Sysex Program Change
• Intermittent incorrect FX Delay Times after a series of rapid Program Changes has been fixed.

• The LED indicators for Realtime Controller Knobs I-L now work correctly. Conditions where the LEDs would not light have been resolved.
• Interrmittent Fatal Errors in the Bank Copy screen have been eliminated.

• New feature: Tempo Based FX B Delays.
• Improved signal-to-noise reverb microcode.
• Improved Note-on velocity ramp-up.
• Tempo controller now works in MIDI Omni mode.
• The unit no longer hangs when using Tempo-based filter envelopes with repeat on and sending a MIDI controller to control FEnvRts.
• User data corruption problems when sending a tuning table with a table number higher than the number of user tuning tables in the unit have been eliminated.
• Assigning presets to channels via individual SysEx parameter messages now works correctly.
• Sysex Copy Preset message now correctly copies all parameters.
• Sysex Dump Preset Common parameters message now processes all parameters correctly.
• Sysex tuning table dumps no longer ignore the last note value.
• Sysex single note tuning changes no longer divide the fine tune number in half.
• External tempo calculation jitter problems have been fixed. Also the Tempo screen now updates correctly when using external tempo.
• RANDOMIZE preset screen no longer always displays USER as the SIMM ID even if the preset on the basic channel is a ROM preset.
• Supports new motherboard hardware (PC-10182).

• If you update via MIDI download the CRC is 2F7577ED.

• "User / (not installed)" no longer shows up in the Demo screen.
• The MIDI "Reset all controllers" message now behaves differently. A message with parameter value = 0 resets only the pitchwheel, mod wheel, pressure and footswitches. A message with parameter value = 127 resets all of these plus volume and pan. Messages with any other parameter value are ignored. The controllers attached to the knobs are no longer affected by Reset All Controllers messages. This fixes a user complaint about using Proteus 2000 with Cakewalk, which by default sends a Reset All Controllers message after every 'Stop' command. In earlier Proteii software, this message set **all** controllers to zero, which tended to cut off the filters and have other undesirable effects.
• FX cords now behave correctly when switching between presets. An example of this was switching from the 2nd preset "kb4:Yo My Dynos" and the 1st preset "kb1:Dynamic Grand"; the piano sound would be incorrectly sent to the delay effect. The problem occurred when switching to presets that had a controller routed to an FX send in the FX cords, and also had that controller's initial controller value set to zero.
• Problems with a newly selected preset's initial controllers affecting held notes when switching between presets have been addressed. This was easily heard by turning on Audition or just holding a chord and then switching between presets. Held notes were usually undesirably affected by the new preset's initial controller amounts, causing notes with long releases, lowered filters, etc. Now Controllers A-H only affect held notes if that preset is the current preset on the MIDI channel.

CRCs

• If you update via MIDI download the CRC is E9EDC219.
