Will stream 2 midi ever be possible?

[guyman]

Without sampling / converting to float?

What is keeping us from having a prim that can take mono/poly/stream data and converting it to MIDI directly/ reliably/real time?

I've seen ruby implementations, but the cpu & latency it takes to create a frame of a mono, and feed it to ruby seems silly. Isn't this sort of stream clock the backbone of all daws?

The ruby clock doesn't function the same across all rates, so a ruby clock isn't the same as a stream clock.....

Correct, a Ruby clock isn't the same as a stream clock. But you don't need a Ruby clock.

Ruby is snyc'd to sample rate, when either you're working with ASIO out in your schematic, or use your plugin in a DAW. This is possible, because in reality something called double-buffering is going on behind the scenes in Flowstone. We are working on a buffer, while another buffer is sent to and processed by the DAC.

We just don't get to see it, because it is much cooler to actually work "sample-based". But you shouldn't forget about the real mechanic in the background. Because of the buffer, you can work sample-precise with Ruby as well (this is also explained somewhere in the user guide). Of course, the time Ruby needs to achieve something, needs to be shorter than the time a buffer needs. The time of a buffer can be calculated from its size. For example, a 256 samples buffer at 44.1 kHz covers approx. 6 ms. That should be enough for Ruby to create a MIDI event and send it.

For larger tasks however, Ruby will fail with a too small buffer. Look at your ASIO buffer and try to find a setting that covers, whatever you ask Ruby to do.

If that's the case (if i even understand you correctly ) why isn't there a fool proof step sequencer in ruby? why don't I see ruby oscillators? can I generate realtime index clocks in ruby? sync systems to ppq in ruby? adsr?

I guess to get the functionalities I have imagined in my head, I expect to create 2 ticks/clocks at any fraction of sample rate, one in ruby, one in stream/dspcode, and trigger them simultaneously, they should run in complete sync without question?

How do I do that?

[guyman]

I don't know if I'm communicating effectively.

I want to generate midi events reliably, like in the fl studio step sequencer, using data obtained from streams... or ditch streams for "ruby streams"???

Thank you for your responses.

[tulamide]

Yep, that's what I understood as well.

As I said, the crucial part is the time you have to get Ruby do things. And that isn't much time. That's why you can't see full blown sequencers.

[guyman]

Well to hell with ruby !
Will flowstone ever translate stream into midi signals?
Am I lost in a sea of ignorance?

I want to run a custom clock that then runs a step sequencer... like a daw... any inaccuracy is unacceptable..

I'd love to run a stream into a prim, a set of scheduling commands/data sets... and get midi events on the other side... wholistic latency is acceptable, but things being off AT ALL would not...


a dream I suppose.
