Re: [korgpolyex] Velocity sensitive

2009-01-09 by Michael Hawkins

Which MG depth? DCO or VCF, resonance MG or FM-800 MG?

The list could get so long that there's no way the Poly has the cycles to handle it.

In fact, I really think the Poly is probably only capable of handling one at a time. Otherwise, Poly notes will sound half an hour after they were hit.

So I have split the velocity features into two groups.

Group 1 - technically simple and not CPU intensive
Vel > filter cutoff
Vel > resonance
Vel > FM-800
Vel > EG3 depth
Vel > VCF MG depth
Vel > DCO MG depth
Vel > harmonics mapping
Vel > oscillator detune - *** I doubt I would ever use this  - vote to remove from list

Group2  - technically complex and CPU intensive
Vel > EG1/2 attack
Vel > EG1/2 decay

Vel > EG1/2 release
Vel > LFO speed - *** I doubt I would ever use this - vote to remove from list
Vel > LFO waveform change - *** I doubt I would ever use this - vote to remove from list

Vel > oscillator interval - *** I doubt I would ever use this - vote to remove from list


I am working on other features at the moment so there is no rush to get this all agreed upon in a day or two but I would like to see everyone put their two cents in and work on this list.

Another thing that is out floating right now is getting EG4 created and working. I am beginning to think that there simply won't be enough CPU cycles to do it at all. One way to get CPU cycles back would be to change the EG's into ADSR instead of the ADBSSR Korg type. Who would be disappointed if we just made them into ADSR?

Mike.

Your priority list looks good. Has anyone mentioned Velocity > MG depth?
Also, I might have missed something earlier, does the Hawk kit disable the sequencer?

The only part of this list that is not doable given the CPU cycle constraints is probably the one most ppl might want the most which is...

Velocity to Amplitude. I can't do this because it would require a massive rewrite of the code and a massive increase in CPU cycles (of which there none to be had). I don't think it's worth doing break point, sustain level etc and the math is so complex, I don't think I want to take it on anyway.

The rest I will parse through and think about, although most of them look doable on immediate examination.

What's more important though, is that everyone that has a HAWK kit now should try to put all of these into some sort of priority.

So here I post the list again (with my suggested priority) but now can people reorder them and see if we can come up with a consensus on what should be done first.

Hi,
 
*Vel > Eg 1, 2, 3, and 4 Amplitude (not 
sure if this is the best techie way to describe it but, basically, the harder 
you hit, the louder it sounds/the more the VCF opens up/the more EG4 affects 
global pitch/noise)
 
*Vel > all EG steps (att, dec, brk p, slope, 
sus, rel) or at least some of them
 
*Vel > filter cutoff and reso
 
*Vel > FM-800
 
*Vel > oscillator interval
 
*Vel > oscillator detune
 *Vel > LFO speed
 
*Vel > LFO wave change
 
*Vel > "muting/unmuting" the different 
harmonics? Say, play lightly, only first harmonic is heard... play harder, a 
more sawtooth-like sound 
is heard as the remaninig 3 harmonics are engaged. 
Dunno if it is feasible, though.
 
(if any other ideas come to me, i'll let you 
know)
 
BTW, all the above should be possible to be 
assigned both positive and negative modulation on the targets. Also, some sort 
of keyboard tracking would be cool.
 
Who knows? maybe the Atomahawk 800 will end up as a 
poor-man Oberheim Matrix 12? Ha, it feels so nice just asking The Man for 
more... like a kid in a candy store...

OK, this is great feedback.

I've been making good progress going  back over my code and collapsing certain parts of it into reusable functions  so that the memory use is actually dropping right now.

I also have been  thinking about the ARP too. It is not on the top of my list that is for sure.  I think a simple ARP is a good idea for those of us who don't use computers or  a hardware sequencer. But how many of us are in that position?

Since I  was able to get the sustain pedal working and actually change the EG1/2  sustain in real time according to the pedal, it is now quite possible to  change any part of the EG parameters according to velocity.

I believe I  can do the same for EG3.

So I can see that altering attack on EG1/2 or  EG3 might be things we'd like to change according to velocity.

What  other parameters might we want changed according to  velocity?

Mike

i'd say the HAWK-800 is well on the way to "killer" without a sequencer  or 
arpeggiator. somewhat disregarding my own personal wish-list (LCD &  sysex 
for panel events), i think velocity sensitivity is the *only* thing  the 
kit is "missing".

100% agree.
