preenfm2 and preenfm3 / Re: PreenFM2 More Waveforms Like the Ableton Live Operator?

« on: January 16, 2014, 11:49:14 AM »

To be honest, FM is less about the starting point (the waveform) and more about modifying the waveform with modulators and algorithms.

What 6581punk says ;-)

I  don't know how can change the waves from source code!

That's not the hardest point.
Give me the table required in step 2 and i can compile it for you.

Expected format can be seen here :
https://github.com/Ixox/preenFM2/blob/master/waveforms/waves.c

You'll have to investigate and work on your own for this step 2.

how can make the saw d wave into preen fm to make a dub stabs?

1 - Get the PreenFM code on github.
2 - Get one cycle of the "saw d" wave,  turn it into a C float array of 1024 or 2048 values between -1.0 and 1.0.
3 - Modify the wave.c files and replace one of the waveforms buy yours.
4- recompile and flash the new firmware

Easy ? No ;-)

Don't know about Operator.

But the preenFM2 wavetables are in the fast access memory of the MCU.
The available 64kB  are already full.

Thanks again for the report and investigation.

Thanks a lot for your quick responses.
Yes midiclock while browsing this bank crashes the Preen... I could reproduce that.

Will fix.

Thanks for the feedback.

Martin, your PreenFM2 looks Great !
White box + black letters + this classic green LCD ! Nice choice.

How did you do the black letters ?

Thanks for the aditionnal information.

That seems to be a bug in the PreenFM2. Whatever the midi info are, it should not crash.
I'll try to find information about the ZeroSL midi clock out.

To isolate the issue, can you try to remove JMP2, so that the USB does not power anymore the PreenFM, put JMP1 on.
Plug an USB cable to your computer AND the power suply DC.

Is it still crashing ?

Or it can be because of weird/parasite USB midi bytes ? which would explain why your stack targets new midi byte procedure....

Let me know if you find something new.

New thread created from messages about this problem.

The 5V provided by your PC can be too weak for the preenFM2.
Is it a laptop ?

Interesting, let me know...
Did you get normal "making price" (in addition to the price of the sheet) for the box ?

Thanks.... But it works perfectly here with "0.9o o" firmware. 

Several questions :
1. It always freeze on preset 3 exactly ?
2. Other banks don't have any problem ?
3. What if you browse preset with Enc 2, 3 or 4, it should jump over preset 3 ?
4. Can you browse this preset with the save menu. Menu->Save->Bank->Funky12.BNK then browse the preset name.. The difference is that in this case only the preset name is read.
5. Rename the bank on your computer (Funky13.BNK for example) , than copy it beside the other one on the PreenFM. Same problem when loading preset 3 from Funky13.BNK on the preen ?

Thanks for helping me to understand,

Xavier

Ponoko powered companies (razorlab, formulor) seem to not really accept Inkscape svg file dispite they claim they do.
I've ordered an old version of CorelDraw and i hopefully will be able to provide SVG files they can read.

I've seen an example of the problem, the MIDI socket holes go a bit pear shaped.

What have you seen ? with what app ?

The more people upgrade their bootloader to 1.10 the less i'll hear about dfu-util problem
