Shuriken Posted November 25, 2011 Report Share Posted November 25, 2011 Although not a full blown kit, there is something similar going on here: preenFM seems to be using the internal DAC though. Quote Link to comment Share on other sites More sharing options...

peterpressure Posted November 25, 2011 Author Report Share Posted November 25, 2011 Ckeck your browser, works over here. Even tried it on my Android phone. I just get: An Error Occurred Sorry, an error occurred. If you are unsure on how to use a feature, or don't know why you got this error message, try looking through the help files for more information. #10342 We could not determine which forum this topic is in.

ilmenator Posted November 25, 2011 Report Share Posted November 25, 2011 Even tried it on my Android phone. Well, mobile browsers have a tendency to be even less cooperative... But the problem is a different one: having another look I found that the link points towards a restricted section of the MIDIbox forum where only users with programmer status have access. It is mainly about a beta version of the nI2S synth running on the STM32 core. Quote Link to comment Share on other sites More sharing options...
Shuriken Posted November 25, 2011 Report Share Posted November 25, 2011 (edited) It's in the Programmers Lounch section, which you probably dont have access to. Sorry about that. Edited November 25, 2011 by Shuriken Quote Link to comment Share on other sites More sharing options...
peterpressure Posted November 26, 2011 Author Report Share Posted November 26, 2011 It's in the Programmers Lounch section, which you probably dont have access to. Sorry about that. Its ok, maybe someday I will have access if I prove my worth around here... :sorcerer: Quote Link to comment Share on other sites More sharing options...
Ixox Posted November 26, 2011 Report Share Posted November 26, 2011 Hi, I'm still coming here from time to time to see how things are moving forward ;-) I learnt so many things from Thorsten work. The 24LC512 and 75HC165 wiring of the PreenFM come directly from the midibox. The audio output do not come from a DAC but from a 1 bit digital output at 72Mhz low pass filtered.

TK. Posted December 11, 2011 Report Share Posted December 11, 2011 Stumbled upon this in the Raspberry PI forums: http://www.raspberrypi.org/forum?mingleforumaction=viewtopic&t=966 DIY PreenFM synth: http://sites.google.com/site/preenfm/ Really great work! I like the assembly hacks, very inspirational! :) Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Ixox Posted February 13, 2012 Report Share Posted February 13, 2012 I'm a bit late on this one... But thanks Thorsten, i'm glad if you find something useful inside. For those who can be interested, lots of new things since 2 months. - It now has 2 step sequencers usable as source in the modulation matrix. - External Midi clock synchronization for the 3 LFOs and 2 step sequencers - Kind of gate on the main output That allows to get sound like this by just pressing a few key on your keyboard : http://xhosxe.free.fr/PreenFM/PreenFM_MidiClock.mp3 (Drums are VST Drumaxx). No assembly in the new feature ;-) Xavier Quote Link to comment Share on other sites More sharing options...
