Reverb??

[ErichHeinemann]

Hi Marcel,
I have tried to add the Reverb from the Sampler to the Synth - it simply crashes.
I tried to replace the Delay with the Reverb - it does nothing?

Before the ESP crashes, a beep with reverb was created but that´s all.
I used Your original code.

Any idea?
I added the needed Variable int the config.h
SAMPLE_BUFFER_SIZE=64

In Setup:
Serial.printf("Initialize Reverb Module\n");
Reverb_Setup();

In the loop, I did this:
Reverb_Process( &fl_sample, &fr_sample, SAMPLE_BUFFER_SIZE );

Any suggestions? I simply wanted to try the reverb as an alternative.
Would it be possible to add the BiFilter from the Drums too?

Hi Erich,

yes it crashed because of accesing memory which shouldn't be used. The synth project doesn't use a sample buffer. You can try to use
#define SAMPLE_BUFFER_SIZE 1
In addition to that please check if the memory allocation is successful. There are places using malloc and some memory is allocated as static RAM.

Yes I think that should work. Each feature will cost processing power limiting the max polyphony at the end. But it might work

Hi Marcel Keytracking: voice->velocity = vel * 1.25 - (note/500);// 0.25; /* just something to test */ Reverb copied from the Sampler: -> Sounds great with Unison!! Fat fatter! And Delay works still fine too! Reverb_Process( &fl_sample, &fr_sample, 1); Works perfekt!

I will test the reverb too...good idea.
How many poly voice did you have Erich....for me it is just 4 in poly mode...i will try to add a paraphonic mode also

I was only using „Unison“-Mode with 3 fat voice - Sounding like the „JUMP“-Solo .. was enough for me. Do You have any suggestions how Ground or Pin 2 has to be connected on die MIDI-In-Connector? Normally it is not connected, but yesterday I had issues with the Novation Circuit, using its MIDI Out and connect to the MIDI-IN drove the ESP32-Synth to craziness. I had to add a CAP 2.2yF to ground to get proper MIDI-Signals back. Same Schematic worked fine with my Yamaha Keyboard. .. it is only the Novation Circuit doing wrong things. Best Regards Erich

Maybe you must try to record what the Circuit send to his midi port (try this https://mountainutilities.eu/miditools).Could you add a schematics for all you mapping issues ?
