If you like old Sierra games and making lofi music + having and old PC with Soundblaster 16 or atleast the same midiport you can use this dos program to play instruments used in the music of the MT-32 versions of the games. Download Sierra Sound Library + buy an Roland MT-32 with an old dos-pc. Also working with Dosbox if you dont have the correct interface :p
The Roland D5 might be the smallest LAsynth keyboard but not small enough :p
I stripped the keyboard and the joystick + moved one of the boads ontop of the other and it became approx 10times smaller (after using a metalsaw) :p perfect for digital sounding stuff like blipblop bitpop chiptune 8-bit tracker lofi electronic pop and similar etc..
Mode Machines SiD is a good looking box with a two channel sequencer. Good for when you want unexpected results and you dont know what youre doin, if you find one cheep you can try it :p not the best c64 synth but fun anyway.. The editor is made in java and you need a faster computer then i have i guess to run it smoth? Mine is 10years old running winXP.
