Any way to make a trigger that occurs on patch load??

TheRain

Hi guys, I've been trying to think of a way to trigger something just once at the load time of a patch. I thought perhaps the one shot mode would do this on the sequencers if I put a pulse through the clock... maybe it would play once through when I loaded the patch... but unfortunately this did not happen. Any ideas???

It should be possible to use the status module for it, this is what the online help has to say about its patch active output :

Actually, nevermind... I figured a way. If you send a constant value through a short delay, it will go from low to high as soon as the patch loads. Here's an attachment that triggers an envelop and allows sound from an osc for just a few seconds when the patch loads... indicating that you can use such an envelope and adjust the hold time on it to how long you want the load trigger to last.

If you've seen the real time-sampling trick that allows you to sample something into a delay module and play it back with complete control over things like playback speed, forward/reverse control and sample playback start postion... you might understand the use for this load trigger.

Essentially what you could do is, for instance, set up some drum oscs and upon load of the patch you could set up the patch to automatically sample the drum sounds into the delay, then you can control the playback speed and reversing and such.

Well you did the same in your patch, you can leave out the delay though.

it wouldn't work without the delay... or even with a shorter delay than what's there.

Say, do you know if anyone's posted a variation of the delay sampling technique with sample reversing and things?

Funny, I tried it and it works here without the delay, and it should, it always did ... are you using the demo ?

I wouldn't know about sample reversing, you don't mean frequency shifting I guess.

No, I'm using the G2 Keyboard. I'm gonna search around the forum and see if anyone else has posted a patch like this and I'll post it in the experimental section if I can't find it. Basically what I have is the patch has a simple drum sequence in the synth section and then a delay sampler in the fx section... when the patch loads it triggers the delay sampler to sample the drum sequence... then when you hit a key the sequence plays back from the sampler and I have knobs set up to switch to reverse play in the middle of playing and to adjust the speed of playback.

Yes please post it, we seem to be talking about different things :-)

Reversing is a little tricky with the current group of delay modules.

Edit: Ha Ha, the patch you posted does reverse playback very well. How did I miss that? Embarassed

I posted this http://electro-music.com/forum/topic-6072.html which seriously messes up loops. Sometimes short sections seem to be reversed, but it is a little unpredictable. Rolling Eyes

It is a 4 phase version of the classic pitch shifter with bigger than required delay times.

Thanks guys. So I posted the reversing patch to Experimental patches if you want to take a look. Where I really want to head with this is some more flexible wavetable sequencing type stuff where the waves are "sampled" on patch startup into separate very short delay modules and then triggered as oscillators. But I like this patch as well, it is like the Machinedrum UW's RAM machine, which I am also a Machinedrum user, but am in the process of selling it so it's cool to be able to replicate some of it's functionality.
