Hey,
I have been messing with ticks again, with the goal of midi sequencing. Here is an example->
Please check it for me if you like. It seems plain that when you send a tick to multiple sources you get more ticks, but they are in packets, not sequential. So I used a tick divide here. I think they are 1 increment steps now. Maybe we can use windows timer ticks if this works. I will stick it in a sequencer and see how close to sample accurate it is and add that to this thread 😉
It's not a great idea to display the climbing tick, it sucks a lot of cpu, but you can tell that it is not a multiple of any 1 number, and hence a packet, when you start and stop it a few times.
Cheers folk, hope the example doesn't disappoint. I'm not sure how we will fare CPU wise when it is built into a sequencer.

Sorry for being negative -I wish there would be a quick solution, but your idea doesn't work at all.
Proof: just click on the schematic background and the counter will stop for a split second

I imagine that means you won't be able to play live with it. It will be sampling a stream though, so it will correct again when you stop editing? I play with it today and see. No worries being frank, I sorta guess this one is for the devs to solve, and not a tinkerer like me 🙂

I will do some more experiments, but 16th notes sound like they are in time. I will make a little audio example. It does go out of time , not when you click the plug, but it's window in the host. Then you can stop and play again and it will sound in time. I try a few more recordings to see how close it is.
Edits:
Without hooking the fast tick up to a redraw, there is no improvement further than tick100 prim . If you hook it up to a redraw it uses 1 core of my quad3 machine. It's weird it needs a redraw to kick in. Anyway it's pretty good timing with the redraw, like perceptibly 32nd notes are not drifting. I guess they are like 100 samples out, but they sound fine to the ear. I will up a sequencer that uses this soon. I can't figure out how to get rid of the redraw 🙁 I've tried drawing nothing and drawing no area. Anyway, stay tuned for audio demos and sound forge pics
Yep, I won't bother sound or pics, I can up the .osm though if anyone is curious. It is 100 samples out at worst at 44100. Unusable though for the redraw uses too much CPU.
OK, I wasn't doing much else so here is the example->
Here is a screen showing how much it is out->
Here is some recorded audio->
I guess play the audio if you are curious. It seems fine.

Great job Nix, this one is alot of fun. Thanks for sharing. 🙂

Thanks for sharing Nix! Sad to say, but on my XP laptop (very old) the timing is not even near your recording. It keeps drifting randomly all the time. Even I can play more rigid live and I am not very good keyboard player. I Could not see any abnormal spikes in windows CPU-meter.
I have almost stopped using SM because I get hiccups in almost everything I do and I have no faith in it getting better in near future. I am not able to finish my projects, they are just toys that sometimes seem to work and then don't.
I hope you (or someone else) finds a solution to accurate timing. I have tried various methods, but have not found a good one.
Keep up the good work!

I would give up on SM if you need green or MIDI timing. Audio code is rock-solid though.

I hope something works for you soon Sasu, if you want to up one of your projects in help we could have at it.
What I think you might need to do here if you like is: delete the module that has only the mgui and redraw in it. Then hook up a float readout instead. Now it should take all your CPU and have better timing. It's hacky for sure, I had to do that when I opened the project just now.

Yes, the audio code works fine! I do like the program in general but I really wish there was a sample accurate way to trigger MIDI.
