How long latency if I

6 posts in this topic

How is the latency of a PIC8-core if I use till 320 switches (in DIN/DOUT matrix of course)? Thanks

It depends on the software but it can be very low, i.e. not noticeable.

Which software is then better? I have no idea. I checked for MB128 that this goes with MIOS-Studio, but how do you say to MB that the DIN-DOUT makes the notes and the channels etc?

I read from a magnet producer (Wicks, I think) that they lower the opening time to 60ms. That lets plenty of time, doesnt it?

There is no "mature" matrix input software for the 8 bit MidiBox. You have to be pretty comfortable with assembly language coding and be prepared for a lot of work to do matrix input on the 8 bit platform. I would recommend using the 32 bit platform and the newest MIDIIO128 software for matrix input.

60ms seems slow if you are talking about opening a valve under a pipe in a pipe organ. You'll notice the delay once it starts getting above 20ms.

Dear Jim, well this is not for me then.

About the LPC, this is exactly what I prefer, but till now I come to prices more than 2x higher that in the US. They charge $100 for one LPC, $200 for 4. Not the LPC is the problem, but mailing :-( Even the official NXP-reseller here doesnt get it better.

So I stay at smthg like 3x MB128-MIOS8 in chain and a 4550 as MIDI-USB. Just beginning right now with soldering my first works, anyway...

All would change if I could convice friends here to bring it back from France, Germany or Miami in their bag.

The parallel inputs of a chain of MB128s may not be elegant but it is as solid as a rock and about as easy as can be to troubleshoot. I've seen a lot of people successfully complete very impressive projects rather quickly with this approach. There is a lot to be said for using something simple, even if it uses more hardware, when you are doing a one off project.

I've also seen quite a few people spend a lot of time trying to be clever by using matrix input without ever completing their project, myself included.
