I use a gba sp with nanoloop 2.7.7 and the gba sp is slave sync to the volca. It works fine.
The cable is made by duality micro.
No skip for more than one hour.
Try another gba maybe.

I have not try to do it with LSDJ.
But with nanoloop to be able to sync slave nanoloop to a volca is really a great bonus.
Arduino is great, but what I like with the analogue sync is there is only tempo and no start/stop.
It seem to be not that great at the first look, but really it's way better.

Hi, your cable are great.
I've tested them this week, but you should tell that it is for slave sync.
It took me 5 minute to understand what was wrong

I'm not a gba expert, but this documentation seem to say the old sound register are available.
I think fat use directly this register : http://belogic.com/gba/registers.shtml
I'm really happy to see this guy on the youtube video, he made a good job.

Hi Domu,

here it is, I was pretty busy and I'm still busy, but I'd like to provide a new version with the LFO and PitchBench on picodrum which try to sound like an ER-1, it's not exactly a korg ER-1 but you can make pretty similar sound.
Seem to be stable, so backup the last one and if you had crash just tell me.
This release is only for the PSP version, and it is the tagged version 0.65.

For PBSynth :
you have to modify the EnvAmount and the T/N parameter of the PBSynth to make it sound good.
T/N is the trigger time of the NoteOn and it is in the ENV section, X is the amp, Y is the Trigger time.
ENVDepth is the amount of the filter ADSR enveloppe sent to the VCF, this parameter is located in the VCO section.

For Picodrum :
There is now two LFO, The first one is a FM one which modulate the second oscillator with the first one.
The second one is a kind of PitchBend but not limited to -2 +2, it can go from -88 to +88.
The Two LFO can be used together.

Hi Rot, sorry to be annoying like this.
Furious advanced tracker and M4G were promising tracker on gba and source were near lost for one of them.
prodigy tracker on genesis too but coutsymphony found an old backup by chance.
So it's just a way to keep a backup of the source.
Hope you understand and thank you for your great work, I like it.

There is already a build done, just create the directory PSP/GAMEP/picoloop.
Then unzip the last zip file from this thread in it and it will work.

But if you want to build a new psp binary here is what need to be check in this order :
1) you are able to compile an helloworld => EBOOT.BPB
2) you are able to compile an SDL helloworld => EBOOT.BPB
3) picoloop should build in this environment because you will use the same SDL and the same compiler, but I may have missed something.

First we will check your psp-g++ compiler.

You should have a working pspdev, and we need to validate it.
$ cd /tmp/
$ git clone https://github.com/yoyz/psp
$ cd /tmp/psp/starter
$ ls *
main.cpp  Makefile  psp_callback.cpp  psp_callback.h

Now you have to source your environment variable to see the psp compiler.
In my case I have to launch this command ( I source a file which contain this variable ).
$ export PSPDEV=/home/yoyz/local/pspdev
$ export PATH=$PATH:$PSPDEV/bin
$ which psp-g++
/home/yoyz/local/pspdev/bin/psp-g++

Now you should be able to compile.

$ make
psp-g++ -I. -I/home/yoyz/local/pspdev/psp/sdk/include -G0 -Wall -O2 -I. -I/home/yoyz/local/pspdev/psp/sdk/include -G0 -Wall -O2 -fno-exceptions -fno-rtti -D_PSP_FW_VERSION=500   -c -o psp_callback.o psp_callback.cpp

If this is okay then your toolchain is able to compile a EBOOT.BPB file.
Tell me if it is okay and we will add some SDL stuff in the helloworld.
