Re: Andromeda sequencer problem

2006-11-26 by steffengrondahl

I've investigated the problem futher. 
It seems like the use of sustain pedal and not playing legato disables
the monleg. I get the same behaviour (the sequencer retrigs and plays
notes where there should be a rest) if I disable both monleg and
retrig and does not use the sustain pedal. 
Or to be more precisely:
- config -> kytrig = on 
- config -> length = 4
- config -> lpcnt = sustn or infint
- config -> monleg = off
- trig -> source = pgm key trigger
- trig -> retrig = off
- trig -> mode = normal
sequencer C0 - C0 - A0 - C0, step 4 is a rest.

I press C2 and get
C2 - C2 - A2 - [rest] - C2 - C2 - A2 - [rest] - ... etc

If I at step 3 in the second loop play C3 without releasing C2
C2 - C2 - A2 - [rest] - C2 - C2 - C3 - C3 - A3 - C2 - C3 - C3 - A3 -
C2 - ... etc

Its really strange to me why there's a retrig and why there is a note
being played where there should be a rest. Any logical explanation ?
Or is it just as it is (a bug perhaps) ?

BTW:
I would still like to be able to transpose the sequencer in the middle
of a cycle not playing legato, but having the sustain hold pedal
pressed down. 
Or in other words: 
1) when playing legato (with the keys), having monleg = on and retrig
= off, and not using the sustain pedal (ie let it be up) I can get a
transpose of the sequencer in the middle of a cycle (and no retrig and
rest are not ignored).
I would like the same 
2) not playing legato, having monleg = on and retrig = off, and having
 the sustain pedal being down.
If someone finds a way to do this I would like to know :-)

Cheers (once again)
Steffen

PS: I find the rest a little strange. What does it do ? It seems like
trig/gate is send to the envelopes from a rest (not what I would have
expected), but somehow no signal to the oscillators (but this doesn't
logically not lead to a rest but rather to the oscillators continuing
the same pitch as the previous note). Can anyone explain this ?
