Prophet 600 firmware upgrade: 2022 beta release is now available

Dear all users of an upgraded Prophet 600,

The beta release for the 2022 firmware upgrade is now available! You can download the code and new User Manual here:  Release v2022-beta.1 · image-et-son/p600fw (github.com).

*** NOTE: this is a beta release and it is therefore not the final release but rather very close to it *** 

*** NOTE: the code and manuals come with no warranty whatsoever, you carry out updates at your own risk. Always secure patches before updating the firmware. *** 

Note: in case you're totally new to the GliGli upgrade you would need to modify your Prophet 600. In this case you should consult the documentation provided by GliGli. GliGli's Prophet 600 blog (My Synthesizer stuff: p600fw (gliglisynth.blogspot.com)) contains the links to the technical manual.

If you're already running version 2.0 or version 2.1 RC3 you should be familiar with the upgrade procedure either by USB or by MIDI. Please also refer to the User Manual.

If you want to actively participate in beta testing please drop a comment. I will try to provide help in case of questions but please be understanding that this might not always be possible.

It gets better: Prophet 600 v2022 RC1 (first release candidate)

While I intended to basically release the beta 2022 (2) and only do the smallest and most urgent fixes (hoping of course there would not be any) some very important code changes did came up which now lead up to the improved first release candidate v2022 RC1 ( download ). What happened and what is new?  Apart from those aforementioned small corrections (thanks to the contributors!) there are 2 new features and one really exciting major fix.  The 2 selected features that "sneaked in"were 1) vibrato has now the option to modulate only one of the two oscillators (parameter 222) and 2) the LFO can now be re-triggered when a new key is played (parameter 111) Now to the major fix "tuned pitch shift" : the poly-mod envelope pitch shift of OSC A as well as the LFO pitch shift of OSC A and B are now fully tuned and harmonic. Yes, that wasn't true before. In prior firmware versions tuning was not taken into account so that pitch shifts were detuned depending on how far the...

Revised envelope shapes: inspired by Prophet 5 rev 1/2

Image
The upgraded Prophet 600 offers two envelope shapes: exponential and linear. These are software generated and in versions 2.0 and 2.1 RC3 they are really exactly that: a pure exponential shape and a pure linear shape. Some users argue that a musical choice is somewhere in between. To the ear, the exponential shape drops very quickly at the beginning and then it tails off long. The linear shape on the other hand is thicker in the early decay phase but then it drops hard to zero. The human ear is stunningly sensitive to envelope shapes, even at very low volumes. In a recent nice YouTube video Starsky Carr directly compares the Prophet 5 (rev 4) envelopes to the Prophet 600 addressing exactly this finding:  Prophet 600 vs Prophet 5 // Is the 600 a better value option? - YouTube Now: the 2022 firmware has completely revised linear decay and release shapes, which are linear at the start but then tail off smoothly. To some degree the shape was inspired by the Prophet 5 rev 1/2 envel...
