preenfm2 and preenfm3 / Re: Idea for a new PFM3 FX auto filter

« Last post by Toltekradiation on June 23, 2024, 11:16:38 PM »

Seems like a cool filter trick,
from the Triton manual, i could not find an "auto filter", but there is an "Auto Wah" filter which seems pretty close.

is that this one ?

preenfm2 and preenfm3 / Idea for a new PFM3 FX auto filter

« Last post by matrix12x on June 22, 2024, 11:34:47 PM »

I was recently playing with a Korg Triton... and one of the FX in the Triton would be great here, the "auto filter."

So, its basically 2 band pass filters where one is hard panned right and has panned left. An LFO modulates the cutoff freq of the first BPF and the same LFO but 180 out of phase modulates the second BPF. LFO waveform is the "random" waveform. resonance/Q is set relatively high (but not self oscillating).

Parameters could be:
LFO Rate
Mix (mixing filtered and unfiltered sound)

How this differs from using the current BPF and modulating that using the existing LFOs is the second BPF being modulated 180 out of phase with the first one for a nice stereo effect and the "mix" parameter. this gives a good amount of motion to pads. In the existing BPF, you can't mix the un filtered sound with the filtered sound.

Thoughts?

I would probably start with the existing BPF code.

Hi,

I know it's not very clear.
But from the midi doc (https://ixox.fr/preenfm2/preenfm/midi/) :

Program change
Bank select (CC#0) and Bank Select LSB (#32)
Preenfm bank : CC#0 = 0 then  CC#32 = Preenfm bank number
Combo bank : CC#0 = 1 then CC#32 = Combo number
DC7 bank : CC#0 = 2 then CC#32 = DX7 bank from 0 to 127
DC7 bank : CC#0 = 3 then CC#32 = DX7 bank from 128 to 55

So to access Bank2, program 26 you should send :
CC#0 = 0 (optional because that's the default)
CC#32 = 1 (for Bank 2, it's 0 based)

Then program change will select the preset in Bank2.

Hi,

Only 4104 bytes Sysex file are compatible. I think there are other sysex with different sizes and they won't work.
They must also have .syx extension.

256 is the max number of DX7 file you can have. Because they are pre-read and filename are in memory.

Reminder : The first FAQ of preenfm3 also applies to prrenfm2 :

preenfm2 and preenfm3 / Preenfm2 Program Change messages only works on Bank 1?

« Last post by Esppse on May 17, 2024, 07:36:31 AM »

Hi,

I have programmed a midi controller to do bank select and program change messages.

I have successfully made the bank select part of it. With Program change, the unit only goes to the correct program when it is on Bank 0. When I select any of the other banks, PFM2 does not change programs. I am on the latest 2.21b.

Is there a way to access remotely for example: Bank 2, Program 27?

Thanks

PreenFM1 (the blue one) / Re: Firmware 2.00

Hello

Is there a repository for all the old FreenFm Mk1 information, most of the build links seem dead?

I have just discovered an unboxed Crystal PreenFM kit I bought in 2012 but never got around to building.

Here's a noise/drone piece I made today, running one of my favourite PreenFM2 patches through the FX track of my Analog Keys, modulating the performance controls via CC.
