Another Sequencer (for drums)

hello again....

after almost completely giving up on my other sequencer, I have decided to start again but with a more simple idea, this is a 4 gate out drum sequencer, it has tempo setting, shuffle, and random population options, the steps are programmed using buttons to turn them on or off, there is a cycling LED that will show the current step. step length can vary from 1 to 64 steps per gate, so gate 1 can have 8 steps, gate 2 can have 14 steps, gate 3....... you get it. this can allow for some interesting rhythms. there is currently no option to vary the length of the gate out, other than to have a lower BPM, I don't know if this is necessary, as if it was REALLY important, you could use this device to trigger an adsr with a longer time on it.

anyway, heres the current incarnation.

Cool

Will you add more features or is it done?
My sequencer has the option to vary the gate time, but i also found it a bit useless. I then put a switch to select gate or trigger, just that.

What happened with the other sequencer?

the other one got very complicated, I lost a massive chunk of the code and got disheartened, I may revive it sometime, but got a load of other stuff on the go at the moment Very Happy

thanks for the interest.
I don't think it will have any other features, im considering a reverse function although I don't know how useful that would be Very Happy

ouch...

that's fine, if we keep adding features it'll never end... The only thing i could think that would be cool is the option to save patterns

I'm not sure at the moment, this would mean I would have to get the schematic up to date and everything, then answer questions like "why isn't this working" Very Happy

ill consider it over the next couple of weeks (it still needs some tweaks anyway)
