Decent looking kit...

Although not a full blown kit, there is something similar going on here:

preenFM seems to be using the internal DAC though.

Link does not work for me?

I am stumped, I tried 3 browsers on 2 computers...

Ckeck your browser, works over here.

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.

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.

[Shuriken]

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:

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.

Ixox: Simply ask TK to get access to the Programmer's Lounge and you'll be able to see the thread.

Really great work!

I like the assembly hacks, very inspirational! :)

Best Regards, Thorsten.

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 :

(Drums are VST Drumaxx).

No assembly in the new feature ;-)
