Re: [CZsynth] way to sync vibrato to midi?

2002-09-20 by xpander

The Ensoniq EPS samplers had LFOs that would change rates depending on 
how many notes you were playing... so a "30" rate would be slower when 
you played more keys- Impossible to make a table with. I assume the 
Processor was being taxed- and slowed down this process when more notes 
were being played.

I hope the Casios are not like this.
