Evolver OS 2.0 is coming soon

[Ski 1642606170]

Dave Smith is very near to releasing OS v2.0 for the Evolver. OS v2.0 will have some great new stuff! With Dave's permission, here is the list of new features straight from his own document. Note that additional features will probably be added before the final release. Two of the biggest things for me are the individually addressable filter cutoff & resonance, plus, a whole new 4th bank of programs! Two thumbs up! :thumb: :thumb:

 

Evolver 1.4 Changes

 

All updates to Evolver are 100% backwards compatible with all versions of hardware. They also do not affect Programs made on previous versions of software.

 

1) Sequencer Operation - While the sequencer is running, if you hold the SHIFT button when you hit the STOP button, the sequence will continue running until finished (according to the length of Sequence 1), and will stop after playing step 1.

 

2) Program Change - If you hold the SHIFT button while changing the program or bank, the sound will not change until you release the SHIFT button.

 

3) If you hold the SHIFT button while changing the program or bank while the sequencer is running, when the SHIFT button is released the sequence will complete (according to the length of Sequence 1) before synchronously changing to the new program and it's sequence.

 

4) New Modulation Destinations - New mod destination are envelope 1/2/3/All Decay and envelope 1/2/3/All Release. Also individual filter cutoff and resonance. See new table below.

 

5) MIDI output Sequence Destinations - The sequencer can now be routed to MIDI output destinations, including Note Number, Velocity, Mod Wheel, Pressure, Breath, and Foot Controller. Velocity is a special case - it only works if selected as the destination for Sequence 2 when Sequence 1's destination routed to Note Number. The same for Sequence 3 and 4 (Sequence 4 can be velocity for Sequence 3). If velocity is not used as a destination, the velocity output is 120. So, it is possible to have up to 4 note sequences sent out over MIDI.

 

The actual MIDI note transmitted is the sequence step value plus one (since MIDI note on of zero = note off). Note that this is different than the half-semitone when driving the internal oscillators - this was done to provide a wider range of notes. Also, the main Transpose is added/subtracted to the MIDI note output.

 

Velocity and the other controllers are converted from 0 - 100 range to 0 - 127 range for MIDI.

 

6) Clock Mod Sequencer Destination - Another new sequencer destination is clock Mod. It works via a multiplier based on a step value of 40. If a sequencer step is set to 40, the clock speed stays as set. If set to 20, (half of 40), the clock will be twice as fast for that step. Likewise, a step value of 80 will be twice as slow as normal, and 10 would be 4 times faster.

 

Note that overall limits of 30 to 250 BPM still apply; for example, if you have a BPM of 120, and a sequencer step of 10, it will try to go four times faster than 120, which is 480. Since it is greater than 250, it will clamp at 250. With clever choices of BPM (using Clock Divide as necessary) you can develop a pretty wide range of timing possibilities. Also, with sequences of different lengths, it can really get quite wild.

 

The changes are not displayed if you look at the tempo display. Also, if you have MIDI clock input selected, the changes will be ignored; it only works on internal clocks.

 

7) MIDI Note Sequencer Clock - A new clock source is provided (n0t) for MIDI Clock which allows each new MIDI note to advance the sequencer.

 

8) Split Signal Input Mode - A new Ext In Mode (SPL) for split signals is provided that allows a mono signal input on the Left Input with a separate control signal (for envelope follower, peak hold, and clock source) into the Right Input.

 

9) Tap Tempo - A poor man's tap tempo has been implemented. With the sequencer off, hold the RESET button, and then hold the START/STOP button for a count of four; then lift up the START/STOP button in time. The sequencer will start with the new tempo. Note - the actual speed will depend on the Clock Divide setting. The count will match if Clock Divide is set to 4n. If set to 8n, it will play twice as fast as your "tap", and so forth.

 

10) New MIDI Clock In Mode - there is a new MIDI clock receive mode (in-) that uses the incoming MIDI clock, but ignores Start, Stop, and Continue commands. This has been requested to enable syncing to external clock sources without slaving to external sequencer starts and stops.

 

11) MIDI Input Indicator - the right decimal point in the display flashes whenever anything comes in MIDI input jack. Note that it flashes even when MIDI input is disabled.

 

12) New Program Bank - there is now a bank 4 for an additional 128 programs in Evolver!

Awesome, thanks for the news. I'll have to take a minute to really read these updates, but right off the bat, envelope decay and release times as mod destinations is of immediate use to me. Separate filter controls is great too. It's going to take me a minute to really grasp what you're saying about the sequencer modding velocity, but it sounds like it might be cool.
