thawkins Posted July 11, 2018 Share Posted July 11, 2018 Why the hell does a calculator have a stereo audio output though? I must be getting old. Also, is it just me or the sound is still glitchy especially if the guy edits stuff while playing? Link to comment Share on other sites More sharing options...
sweepstakes Posted July 11, 2018 Share Posted July 11, 2018 Why the hell does a calculator have a stereo audio output though? I must be getting old. Data transfer on these calculators is done via a simple 3-terminal interconnect that happens to be a standard audio jack (presumably to keep manufacturing costs down). This is written in assembly so it's working at a very low level and almost certainly just pushing bits directly to the output register(s) - basically setting the voltage of either terminal "up" or "down" every .1 ms (or whatever the sampling rate is).

modey Posted July 11, 2018 Share Posted July 11, 2018 I tried this; it can sound very menacing, but ultimately I didn't have the patience to learn how to use it properly. Great idea though. Link to comment Share on other sites More sharing options...
worms Posted July 11, 2018 Author Share Posted July 11, 2018 check the tracker's manual first if youre going to buy a calc for this you need a usb to 2.5mm cable, the manual recommends which one to get then you need a 2.5mm to 3.5mm adaptor to get audio out Link to comment Share on other sites More sharing options...
TubularCorporation Posted July 11, 2018 Share Posted July 11, 2018 I managed to get both a TI -something calculator and an unopened USB to TI data cable out of the trash 5 or 6 years ago, so I'll give it a shot at some point, the cable's still in a box somewhere in a closet since I moved last summer. EDIT: never mind, doesn't support TI89 Link to comment Share on other sites More sharing options...
GetSquirrely Posted July 12, 2018 Share Posted July 12, 2018 i've seen these before. they look cool, but i'd rather just get a gameboy and learn LSDJ Link to comment Share on other sites More sharing options...
modey Posted July 12, 2018 Share Posted July 12, 2018 yeah imo nanoloop on GBA is all I need for portable music making, maybe coupled with PO-32 or 33 Link to comment Share on other sites More sharing options...
