shmagoogin77 · Post by **shmagoogin77** » Wed Sep 20, 2006 11:13 am

didnt really know where this topic would go so i put it in here
so i was recently lookign at the boss rc20 loop station and thought it was awesome but wasnt allowed to spend $250 on a guitar accessorie so i decided to try and build one. I am gonna build one using 3 ids25120 chipcorders and recorder circuits for 3x overdubbing and a basic stamp as the brians of it even though it is extremely over powered for this kinda prject i dont have any other microcontroller and my uncle just got me a second basic stamp so i have a spare. So im posting here to see if any one here would like to help me out with this prject. i tried posting on diyaudio but they have a stupid thing where u8 have to post like 10 times to make a new thread.
here are some schems and info i have so faR
IDS25xxx recorder ciruits (dont know if the second one will work)

so if any one wants to contribute at all feel free to pm or post here orim me

No idea! We were working on a software based system (by we I mean my friend) but we never really got anywhere. Not like any of us can like beat box or anything.
Music related topic: Anyone know a Homebrew atari synth cart or something? I would like to play some music with my portable atari.

make a tape delay with one continuous loop of tape!

(shouldnt be that hard, just need 2 old tape players)

I think your best bet would either be using an old pc (the way I'd do it if I had one just since I'm kinda lazy) or a PIC with some SRAM and maybe a LCD display.

I'd recommend using a mp3 encoder/decoder chip or some other a/d audio chip so you can store the audio easily in the ram.

Uhh, the Synth Cart for Atari 2600 by Paul Slocum. Get one, support the homebrew community.

It uses two keypad controllers, like from Star Raider.

Is there one I could use with regular controllers or something? Is there a way I could make the keypad controllers?
