can the Time elasticity be modulated, or is it “only” manually settable ?
if not yet ( which i guess) , is this something planned to come ?
The manual says this:
Time elasticity (phasing)
While BPM changes the global playback speed of both projects, you can use the time elasticity feature to change the playback speed of each track individually.
Press bpm to enter BPM popup. Toggle menu encoder until elasticity % is highlighted. Then Rotate menu encoder to change elasticity value (you can also fine-tune the last digits).
For example, if the global BPM is set to 120.00, and you are working on track 01:
set elasticity to 50%: track 01 playback is two times slower = 60 BPM set elasticity to 200%: track 01 is two times faster = 240 BPM set elasticicity to 100.50%: track 01 is slightly faster and will slowly drift out of phase with the other tracks. Phasing is the main concept used in "Steve Reich - Piano Phase".
In Hapax, time elasticity is a way to achieve polyrhythms (two rhythms being played concurrently).
