need help with stepsequencer

TB303 · Post by **TB303** » Wed Sep 19, 2007 8:56 am

i'm building a synth device in SDK and now i like to integrate a (tight) step sequencer for triggering notes into the design.
is there any dev who can help me with it or show me some example circuits.

i spend several days trying all the different sequencer dsp files but have no clue how to get em to work.

thanks in advance

mike

ps,
( if you like to discuss this in private (NDA) please send a pm )

Hi,

it's all in the logic. Google or wiki search for logic functions, logic counter or shift register & you'll come up with plenty of info. Some of the nord modular sites are interesting in this respect (advanced understanding of logic circuit implementations in dsp-land over there). Beyond that you'll need to actually think about it & experiment. It IS possible in the sdk, I assure you!!

Anyway, I see you're quite a new forum member, so welcome!

regards,
Shroomz

thanks,
i am already tinkering about logic circuits to do the trick and reading a lot
Any help with this subject is welcome for sure

I'm a old member under a new name (lost old one) and a scope user for quite some years now.
also worked with scope dp some years ago but didn't put too much effort into it back then because of the sparsely free time on the dp machine.

Regards,

Ah ok, so you're not a new member. Welcome back then

back in the day, i made one for the "micro" synth
it is just a ramp wave which is compared to 16 equally spaced values. and when it is equal it outputs the next step.

you can alter the odd numbered step values to get swing.

I cant remember if i had to use any custom atoms, but it was only DP back then.

what device do you build with an integrated stepsequencer, tb303?
