[sdiy] Sequencers anyone?

[Stewart Pye]

I would say 16 steps and at least two channels, and a quantizer.

If you want multiple channels you could use a microcontroller to scan 
the pot values, store the values and output them to a DAC. You could 
have some scheme for selecting different channels to edit, and if you 
included the hardware for MIDI someone could add it at a later date. The 
downside to this approach is that most simple micros (PIC, AVR) only 
have 10 bit ADC. That would be fine if you always want the output quantized.

If you don't want to use a microcontroller, take a look at Thomas 
Henry's "Superseque". This is a good basis that could be cut back a bit.

Regards,
Stewart.

I want to make something that would be, if not new, interesting enough that people would want. So, I'm thinking sequencer. Yeah, I know, there's lots of sequencers out there, most of the professional ones are really expensive and the DIY have lots and lots of wiring that will drive anyone crazy after a while. Well, I'm crazy already and don't mind doing a lot of wiring, and I want to offer some thing completed that won't break the bank. Something that would be about $250 at most.

What do you want in a sequencer? number of steps, number of channels, trigger and gate outputs, cascadability, individual outputs from each step? sky's the limit. I think the only thing I'm not comfortable promising is anything to do with MIDI... I really don't have the skills to mess with that. I will try my hand at anything else though. And I will offer just the PCB(s) as well as free schematics since this is SDIY and you all are very wonderful people.
