hi everybody

I recently buyed a Korg Monotron.

http://www.korg.com/monotron

that it's a diminute analog synth, just a little smaller than the gp2x.

I'm not a musician, but I like to generate sounds and noise for some audiovisual projects. and something as portable as this was just what I wanted.

as I had stopped using my gp2x for gamming a time ago, I started to wonder what could I get for making music with it (I already knew about a couple of apps).

and I came across some beutiful trackers and sequencers, they're really well done.

but what strike me the most was the lack of a synthesizer =(

even do the trackers and sequencers are useful for making music, I think they don't really turn your device into a musical instrument.

but a synthesizer does exactly that. you generate sound and music with it. and I think that gives another perspective to the device itself (it's not the same to be able to produce something with it, that to just reproduce).

in the archive I found a couple of apps that generate sounds, but they're on an early stage of development, or are just projects

gp2xPd - Puredata
http://dl.openhandhelds.org/cgi-bin/gp2x.cgi?0,0,0,0,6,1861

sbagen
http://dl.openhandhelds.org/cgi-bin/gp2x.cgi?0,0,0,0,8,1406

so I guess this means that the gp2x is capable of doing synthesis of sounds, right?

my programming skills are VERY rudementary, so I ask: it's too difficult to accomplish something like a graphic synthesizer for the gp2x/wiz/pandora?

I came across this a time ago

http://www.drpetter.se/project_sfxr.html

the even do it's not the type of software I have in mind (that is too sfx oriented), perhapps it can be used to turn this amazing little devices we have into a musical instrument.

there are another free synths out there, with the source code available. but I think is gonna be difficult to just port them to this environments. some work has to be done to really use the controls and touchscreen.

perhapps something like a rudimental kaossilator? http://www.korg.com/kaossilator

hope something can be done, I know there is a really talented bunch of people here. that was what convinced me of buying the gp2x already 3 years ago. perhapps something like this can be groundbreaking for the scene, as I said before, I think that it adds another really new perspective to the devices itself.

cheers from Argentina :)
 
well, I looked a little further and I found this

PBSynth
http://dl.openhandhelds.org/cgi-bin/gp32.cgi?0,0,0,0,6,237

for the GP32 console

it's a substractive synthesizer for a that console :)

the source code was once available, but now I can't find it anywhere

EDIT:
http://chn.bplaced.net/index.php?doc=pbsynth/pbsynth.html

source code :)
 
I might try to port it as i am very interested for it as well. ;)
 
I really hope you can do it Grz- :p

I honestly believe that this can be a great addition to the gp2x

I have emailed the author of PBSynth, as his idea was to do an even complex synth, with a sequencer, new wave forms and more osc.

that would be a killer app. I'd let you know if I have a response

I have also found this for the gp2x (I forgot to put it earlier)

SigGen try1
http://dl.openhandhelds.org/cgi-bin/gp2x.cgi?0,0,0,0,8,2835

that uses synthesis in a very rudimentary way (I think, as I was not able to test it yet)

but perhapps it can be of use for someone to develop something better

gp2xPd and sbagen didn't worked for me :(
 
Just compiled it and it work fine, awesome synth, sound good :) , will see to add all the controls to the gp2x tomorrow.
 
YEAH!! :D

you rock man!!

and I was afraid that I was not gonna be able to interest anyone in this stuff :p

looking forward to use this

can I ask you something? perhapps you have an idea, if it's something technical

do you know why the author didn't include a sine waveform?

because I notice that he don't even planned to add it in his next release

it seems odd
 
More waveforms, including noise and custom samples

It is planned i think, anyway, it is well coded and wouldnt be much work to add more waveforms if the app was discontinued or something.
 
oh ok, I assumed he would not include sine, but it's not specified there

as I said, I've emailed the author asking about this, so if I have a response, I will let you know

thanks for all the good work :)
 
Hehe goog old monotron. I played around with that on a big amp recently and the sounds that filter can produce are awesome.

Yeah a good synthesizer for the gp2x is something we clearly needed! Thanks Grz-! More software for the gp2x is always appreciated.
 
Grz- is making a fantastic job porting that synth :)

the GP2X has now become a true musical instrument, beside a sampler, tracker or a drum box

stay tuned to the launching ;)

I've found a couple more synth related aplications, for some other platforms, and althought there is a source code, I don't think they are portable to the gp2x,perhapps some of you can check them out

SoundCells (kind of a game I think, but it's cool)

PsychoSynth (this is really cool; it's a virtual "reactable like" synth)
