Re: QTKB & ASR problem

2007-07-19 by johnrichoux

Hello Jan-H

I tested your suggestion and it works, thanks.

I think I know why my first approach didn't work. I was triggering the sequencer and the
ASR from the same source. So, the ASR was sampling before the quantization was
complete (most of the time). So, I used a 2nd DTG with a little wider gate time for the ASR,
and it works just fine. By varying the gate time I can introduce fewer or more quantization
errors, which can be very interesting. (Serge+interesting=fun!)

So, now I can do either approach. One requires more QTKB channels, the other requires
another clock source.

Thanks again
John R.
