ok, this is amazing, massive props to @Nitro2k01 for making this work with arduinoboy and a DMG, absolutely loving it!

this is pretty exciting, going to try and flash to a cart later!

{edit} ignore below question I could have just read the thread carefully.... d'oh..

"Just out of interest I assume the modded version only works for non GBC? or can I use my arduinoboy and a GBC with it?"

Interesting!

Nah, from the release notes:

http://blog.gg8.se/wordpress/2016/11/14 … loop-midi/

The original pushpin was GBC and newer only. I'm guessing this mod is as well?

Okay, I just tried pushpin_aboy on a GBA SP (should be the same as a GBC I guess) and I didn't have any problems. I also tried it with a GB Boy Color and it also worked fine. I used my 32k cart with both though, not the EMS.

My only idea is to not check the GBC box when flashing the EMS cart. Since the rom is no longer GBC exclusive. It's been forever since I used the actual EMS software to flash my cart though, so who knows.

So, if you don't mind getting your hands dirty and getting deeper in the code, I would recommend looking at https://github.com/AntonioND/gbt-player or go straight to GBDK (http://gbdk.sourceforge.net/). The GBT-Player is built on top of the GBDK code and allows you to load up rudimentary wav files (it wants them in .mod format). You will have to compile some code into a rom to run with the song on it though.

I'm trying out midi control and gameboys. I got an aboy kit from catskull.(Nice. Thanks!) I got mGB and LSDj to do their thing, but I wasn't having any luck triggering  with pushpin.  Catskull pointed me to double check my software version.  I had downloaded the file from github. So I found the pushpin_aboy file blog and flashed it to my ems cart.  I can get it to load on a dmg and I get the garbled graphics and it triggers audio with note on commands. Cool. When I try to load it on a gbc, I get garbled graphics. I push start and the screen goes black. No audio. So what am I doing wrong? When I flashed the cart, I clicked the gbc box like I usually do. I had pro sound, bass boost, and noise reduction mods on the gbc. So I tried it with a stock gbc, same thing.

Has anyone else tried this with this port? I'm using the nanoloop USB adapter and it's receiving note data just fine, but sending values on those CCs doesn't change the WAV sound. I'll give it a shot with the arduinoboy next.

Shameless plug: I can totally put nitro2k01's version of pushpin on the cart that comes with my arduinoboy quickstart bundle: http://catskull.net/shop/arduinoboyquickstart

I could also whip up a nice cable for GBC use if there's interest.

@PainPerdu: really glad to be proven wrong!
will try this out asap!

Whaaaa? I didn't know this had been done!

actually there is mention! you have 32 MIDI controls, 1 for each sample in the waveform:

So you'd send controller data on those CC numbers to change each sample. With a DAW it should be fairly straightforward to set up a few presets and/or automation to get good sounds. (Samples on the other hand are a different story and sound like kind of a nightmare to deal with in this situation!)

edit: looks like the range of values is 0-15 per the spec

Wave Pattern RAM:
54  Sample #0. Range 0-15, a 4-bit sample.
55  Sample #1. Range 0-15, a 4-bit sample.
56  Sample #2. Range 0-15, a 4-bit sample.
..
85  Sample #31. Range 0-15, a 4-bit sample.

Just to clarify, I didn't make Pushpin I just modded it.

rumpel actually no!
Nitro being the beast that he is, modded the rom (straight in assembly from the rom in bgb because why the hell not) to work with arduinoboy and/or the nanoloop midi usb adapter! So I'll wager my Teensyboy should do the trick as well

I'm so eager to try this out.
Just imagine a live setup with a keyboard and modwheel assigned to shift through wave patterns *_* endless possibilities!
