Psy + Goa trance is my bag too. From what I’ve heard of the Analog Rytm demos it is definitely capable of a nice psy kick.

For sequencing check out Sequentix Cirklon - it’s a techno / trance dream machine, brilliant for on the fly sequencing and arranging.

It’s going to be quite difficult to get a full, well produced modern psy sound without a computer because so many effects and other types of processing are used but if you like the “old skool” sound (90s) then yeah should be fine with hardware only.

Peace,
Andy.
