I'm looking for suggestions from anyone who has experience with using a non-computer based sequencer doing live gigs. I sing and play and do mostly solo and duo gigs and have never worked with one. Any suggestions as to models, pros and cons, ease of use, etc. would be especially welcome. I'm thinking used, because I assume they don't make them anymore because sequencing is done with a laptop these days. I don't have a laptop and don't want to buy one just for that purpose, and have to worry about it getting stolen. Having said that, is there any great advantage that I should consider to a laptop and software sequencing, aside from being able to use the laptop for other things? With any sequencer is it possible (and easy) to repeat a section for extended soloing? My keyboard is a Yamaha S90ES.
