hello list. ive somewhat recently begun composing, and also experimenting a little with sound in linux ... so far though i only have a schumann baby grand piano and this gentoo linux workstation. i decided earlier this week to branch out a bit and purchase a synthesizer; and i figured i should poll this list for suggestions. my budget is pretty slim though ... $500 max. new/used ... new/old ... analog/digital ... doesnt really matter to me. i just want rich sounds and plenty of knobs for twiddlin'. :D suggestions? --vord
