About HoustonTracker 2

HoustonTracker 2 is a music editor/sequencer for the Texas Instruments TI-82, TI-83/82STATS, and TI-83+/84+/SE. It allows you to compose and play multi-channel 1-bit music directly on your TI graphic calculator.

HoustonTracker 2 is a complete rewrite of the original Houston Tracker. Like HT, it is developed by utz aka irrlicht project.

Features

• 3 tone channels

• 1 non-interrupting drum channel

• up to 128 note patterns

• up to 64 drum/fx patterns

• sequence length up to 255 pattern rows

• 16-bit frequency precision

• 8-bit speed precision, can be configured per step

• various effects, including:

- L/C/R stereo hard-panning for tone and drum channels

- 8bit duty cycle control

- duty cycle sweep

• 2 user definable samples

• up to 8 savestates

• edit during playback

Nice.

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?

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).

Thanks, learned something new today. :)

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.

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 

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

i've seen these before. they look cool, but i'd rather just get a gameboy and learn LSDJ

yeah imo nanoloop on GBA is all I need for portable music making, maybe coupled with PO-32 or 33
