I believe Scala might do the trick ! On 23rd Mar Manuel Op de Coul announced a bug fixed release version 1.4 .

Agreed.I hope everyone's optimism about what synth makers will do bears fruit. I snuck in the wet blanket thing because the thread was getting a little too happy ;-) One of the reasons I prefer a sceptical view is I'm never dissapointed and I've seen so much craziness in general, almost nothing surprises me anymore. >> It would take mucho >>RAM, @ 100Kb for ea. mono sample @ one second long.

Well, to be more accurate, one sec. of mono 16-bit,44.1KHZ sound should take @86 to 95KB. What's up with the "(remotely?)" bit ? Someone please correct me if I've got something wrong. Plus,most samplers cannot hold 128 samples per "instrument"/channel. You'd have to use more than one channel to set up a 128-note multi-sample instrument. I checked & in Digest 1393 Gary (not David) said : >Also, having worked a lot with sampled tones looped on a single >vibration, which obviously renders them exactly harmonic, I can certainly >attest to the fact that the timbre changes slightly when it drops into >looping.

Besides which, when things get too convoluted the room tends to spin. I'm not much for delayed gratification. Speaking of D.First, a wee article about him in Guitar Player somewhere between 1991 and 1993 (I think) was possibly the first time I read about microtones. They did an article on Glen Branca too @ the same time (maybe). David, I remember reading it with fascination and it's a little weird being on the same list and quoting snippets of wisdom. Later ,eh ? -Drew
