Software wise you had things like Dr Ts KCS, Bars N Pipes, Music-X, other commercially. None of them was Cu-base but those were pretty good. Maff Evans liked them to varying degrees, and he was a very critical reviewer.
Down at the bottom end you had OctamedPro and Octamed SS, or a variant of Noisetracker if you just had a sampler cartridge and no Midi. If you didn't have a sampler, then of course you were collecting samples from every mod and game that you could get them from.
Technosound Turbo was rated as a sampler. Mind you, ANY 8 bit sampler could be off, you needed an oscillocope to calibrate them properly really. Most were pretty close but not quite 127 level when connected to 0dB line.
Most Amiga Midi boxes didn't have a Thru, just in and out.
Perhaps most surprising, ripping audio data direct from a CD hadn't been invented, quite, I think. You just played the audio into the sampler, most nobody had a CD-ROM on a computer until about 95. Decks let you play with the playback speed, double speed tape decks were quite useful too.
