So as part of this project I'm working on, I'm building a simple drum sequencer.

Soon I'll add some synths to it as well and all will be good.

So I thought I'd present some progress and ask for feedback.
Ok, so here goes;
I kind of want a crash cymbal in there, but I haven't quite got that one right.

The hats are the way they are because I read that the 808 had 6 square oscillators generating hats, so I plugged in some arbitrary figures and a decent sound came out.

The snare needs to sound... more 808 ish I suppose.

The stutter switch doesn't sound too nice, but I'm leaving it in for now.

And does anyone have any hints for me to use for generative type sequencing? or will I end up with a non-sensical blargh of sound if i let it run its own deal.

Toying around with the delay, I worked out i could tune my kick with a high feedback and short delay time.
I assume this works kind of on the same principles as ring modulation? (I'm sure obi will jump in with an answer to this)
Would you suggest this as a good way to go about bass synthesizing? I could probably work out some close to tuned pitches if i sat with it.

Any feedback/suggestions/cakes would be greatly appreciated.
(oh, like most of my patches, it seems to have startup problems, but i included a walkthrough of how to twiddle until it works)

edit: also i will need to work on some nice crunchy distortion as well.

What I would do if I were you now is consolidate the patch into a single master patch using the bits as abstractions with proper inlets and outlets. It's a little difficult to get going even with the instructions you give.

The snare is cool for such a simple lowpass + noise, and the delay helps to liven it up (it's more like a resonator than ring mod btw). To get closer to 808 add a burst of pitched (sinewave) about 200Hz

Crash is difficult. A mixture of highpass filtered noise and the square wave hi-hat source should get you into the right area.

As for random pattern generation, a lot can be done with modulo arithmetic, [change] and [moses], plus [urn] is useful.

I once made a "jazz drum" patch that might give you some ideas if you pull it apart.

Otherwise, a list based sequencer with triples {instrument, beat, volume} would be a good start and then figure some way to randomise the values.

Have fun,

Ah, thanks that 200hz wave really filled out the snare.

I was trying for the crash like that, and i was attempting to modulate it with a sinewave.

Jazz drum seems to do pretty much what i wanted, I'll work my way through tearing it apart and creating some horrible offspring from it.
One thing with jazz drum is, that you seem to have a whole load of samples, so would you suggest i set up a bunch of different envelopes? with different attack and release speeds, and different amplitudes, which could then be randomly selected?

How would a list based sequencer work? All the information would be saved in something like a text file and then read out on each beat?

with your sliders, you can click on 'init' in the properties dialogue, so that the values are saved with the patch and reloaded on startup.

...or else use a state-saving mechanism such as memento or ssaad
