Dear all,
hereby I inform you that FW 1.09 passed test and released by Waldorf Music! One can officially download it from the Support section of waldorfmusic.com
The most important changes are :
fixed - multimode MIDI processing for parts on separate MIDI channels now works as expected (Pitchbend & Co issue)
fixed - bug with hi-res parameters (Transition Start / Transition End) in sysex sender/receiver
fixed - UserWavetable load for 16-bit waves β corrupted wave 1 (take care of RIFF chunk offset properly)
fixed - Smooth Scan misbehavior on fast modulation rates (due to fractional overflow)
improved β M now suppresses CC emitting, if a sound parameter was set up via sysex
added - sysex pair 0x60 / 0x61 - M state request/answer (editor support)
added - possibility to update single sound via sysex only in working RAM, do not save it directly to ROM first (editor support)
added - updater function to track bulk sound updates via SYSEX and reconfigure DSP (editor support)
added - updater function to track UI updates during bulk sound updates via sysex (editor support)
added - sysex 0x66 to changing Multi Arrangement (as regular PC/BC messages change the Sound within the Part since FW 1.08)
Unfortunately, due to full used ROM, some bugs can't be fixed until graphic engine will be changed. I am working tight on it, as I want to use the same highly optimized UI engine for my synth too. The next stuff is known bugs and planned to be fixed at next big release FW 1.10, probably in Oct-Nov 2023 :
The MIDI clock drifts in Slave mode. Unable to fix without changing the graphic engine.Β
Proposed workaround until fixed: Use M as the Master Clock source, if possible.
The Multimode could overdrive the DSP in dual mode if voice stealing & glide are enabled. Unable to fix without changing the graphic engine (need ROM space for updating the voice stealing algorithm).
Proposed workaround until fixed: Use the Modern Mode for Part 1, to reduce DSP load.
The Transition replay is sometimes overdriven/clicky for user transitions. The possible reason is overflow due to the interpolator.Β
Possible workaround β use normalization for -6dB gain in transitions to avoid such an issue.Β
On behalf of Waldorf music I am saying big Thank you! for your support, help and inputs. This constant feedback and contact with you gave me invaluable experience of collaboration, support and improving of complex product.
You are also inspired me to go further and continue to design, develop and produce synthesizers. I love it, and I love GS community. Thank you, gals & guys.

You are incredible.
Warm greetings from Remagen
