Just downloaded PD 0.51.1 and running it on Windows10. Got sound working right out of the box, but it has stopped working without me changing any of the preferences. I first_sequencer.pd I've attached my simple patch here. Basically it worked until I added a new message (62) to go into the makenote object. Since then, I've fiddled with different combinations of IO, MIDI, etc. to no avail. I don't know if it's something weird with GS Wavetable Synth of MIDI Mapper, or if I'm missing something super obvious.

I did the audio/MIDI test patch, which worked, though the tone at 60 was originally a sine wave, and now sounds like noise (though I can change the pitch of the noise by changing the number in the message). Maybe that's a clue? But I get a nice middle C piano note when I click the MIDI box.

Totally stumped right at the beginning!

@CrouchingPython There is no error with your patch, but like you probably know already it doesn't produce sound (your patch send midi out to an external connected software or hardware). Media - Test audio and midi is your friend, it will start the DSP and you can test in / out of both audio and midi.

Thanks for the reply!

Yep, I've tried every combo there I can, but still no sound.

Interestingly, the attached file works fine, but it uses the mtof object to convert midi to frequency. So I'm guessing the problem is with something with the Windows GS Wavetable Synth or MIDI Mapper, since those are the only ones available, and I've tried them both.

@CrouchingPython I can't even find a way to open a control panel for the GS Wavetable Synth. Maybe try CoolSoft's VirtualMIDISynth instead?

Thanks for that reply, and I'll look into that.

In the meantime, I got it working by initializing the velocity and duration in the makenote object, as shown in the attached file.

I'm happy that it works, but this makes absolutely no sense to me. If I put the velocity and duration in message boxes and hook them up, no sound. In the makenote object, voila.

simple_midi_testing.pd

@CrouchingPython In your first patch you need to click the message boxes you connected for velocity and duration.
It is only when you click them that they send their values into [makenote].

You can also send all the information for every note separately with a message like [62 127 500( or [61 120 1000( into the left inlet of [makenote]

When starting out with Pd it is a really good idea to find out how it works "under the hood".
In the "doc" folder of your Pd installation there is a manual.
x2.htm in that folder explains what happens with messages and audio in your patch.
There is a lot of help and examples in the doc folder...... it is great bedtime reading... and you will start to feel like an expert very quickly.........!

@whale-av Thanks! I'll start reading that right now!
