preenfm2 and preenfm3 / Re: custom extended firmware

« on: January 20, 2023, 09:39:32 PM »

Hi Xavier Thanks for replying

The 8 timbre version (8 mono instruments) that lokki posted in reply #24. I used this firmware for a bit and found it super useful for percussion plus bass and melody.
It would be great if there was a way to include this in the firmware to choose either a 4 timbre version or 8 timbre mono version.

here is the 8timbres version with the env fix by xavier, currently untested so let me know if it does not work properly.

Hey lokki! I loved this firmware when you first posted it back in 2018. Is it possible you could update the commits on github? Would love to use this firmware with all the new additions. Xavier is this something you would be able to do? I know it's a big ask. This firmware is pretty rad and really extends the preenfm2 in killer way. Thanks!

preenfm2 and preenfm3 / Re: Found a cool trick for using PFM2 as a drum synth (with limitations!)

« on: April 16, 2021, 10:06:05 PM »

I created a quick patch with Kick, Snare, and Hi Hat all in one polyphonic patch. I used algorithm 8 to have two operators mixing them in and out based on where on the keyboard I was playing. So Op 5 & 6 are exclusively for HH. Op 1 & 2 are for kick. Op 1, 2, & 3 are for snare. The Note Scaling and Modulation Matrix makes it very easy to achieve this type of patch.

I've attached the sysex patch and a quick audio demo. Hope this helps

The way I've achieved this is to create a patch similar to the MS20 kick/snare patch. Basically you use velocity or key split to change parameters ie the lower register are kick/tom sounds and the upper register are snare/hh sounds. Super efficient and you could have poly drums on one track.

Hey there! I checked your github but didn’t see the device posted. Any chance you could upload it? would love to give it a try! Sounds great!

Sorry guys I’ve been swamped with studio repairs and life stuff. I’ll try to knock out converting some waves in the coming weeks.

Hi there! I came across your site a few years ago and love the content. Great to see you here.

I converted waveforms from the TX81Z for use on the PFM2 and uploaded them to this forum. If you could record the raw waveforms of the FS1R and send them to me I would love to do the same to them. DM and I’ll send you my email address

FYI for anyone recording waveforms:

Record each waveform at 48k 24bit around 46.87hz or F#1 tuned sharp. One cycle at that frequency gives you exactly 1024 samples.

Amazing! I can’t wait!! I’ll definitely be grabbing a kit when its ready thank you

Will there be an adapter kit for those of us with an already built PFM2? I would love to add this functionality to my PFM2. Is it possible for it to work unracked? Thanks for all of this work btw. Its amazing!

You can also try loading your own user waves. I tried using sampled saw waves from analog gear and ended up hating it for FM purposes. I also tried a more “accurate” saw wave and the reuksts were too buzzy and filled with unwanted artifacts.

preenfm2 and preenfm3 / Arp MIDI CC NRPN Bug 2.08b Xavier & lokki OS's [Fixed in 2.09]

« on: September 08, 2018, 04:00:46 AM »

I'm programming a preset for the Behringer BCR2000. Some of the following also occurs while using the PFM2 Editor.

Sending sending NRPN and CC values for the Arp CLK parameter makes some parameters disappear from the page when all Arp parameters are being controlled with NRPN's.

Sending either NRPN and CC values for the Arp CLK will change the Arp BPM one increment at a time and change the Arp Direction to it's highest value.

Even stranger still, when I send NRPN and CC values for Division and Duration while still on the first arp page I get a garbled mess.

Will sometimes crash as well.

I've double checked the parameter's are not being sent values beyond their limit.

I've attached images below.

preenfm2 and preenfm3 / Re: Non-linear waveshaping on the PreenFM2

« on: February 28, 2018, 02:16:18 AM »

I'm doing a bunch of Chebyshev tables in Mathematica + the ones in Daniel Arfib's paper. Here are some quick tests at 1024 samples => T2 to T13 with graphic plots of the table function. I'll try a few at smaller sizes at some point too. Note that T11 has a big click [which I like of course!] as interpreted by Preen, and I think this is something to do with how the import works. ?? It will be interesting to hear the differences in table sizes too.

&

I just spotted in my little example preset that OP1 is set to keybd, which would also normally be set to fixed for classic waveshaping. Having it track the keyboard will push it more or less away from zero hertz, depending on tuning table.

I tried out your waveforms! It's interesting to hear the different results. Your's are more buzzy which makes me think the amplitude of your output is maybe too high? Mine was set just below the maximum threshold around 90% and as a result my waveforms are less buzzy. Either way this is all really great stuff!

I'll mess around with that fixed/keybd on OP1. Should be interesting.

Also as a note waveform Tx5 in my zip file has an incorrect header at the top of the text file. Forgot to add:
Tx5
1024

I noticed the clicking in my own tests when using the plot points of array in puredata. I come up with an entirely different waveset when I create tables based on audio snippets recorded from the output of puredata which seem to be more accurate for waveshaping purposes. I'll post my waveforms with jpegs below. I'll give your waveshapes a try as well

I also modified the puredata patch to include an oscilloscope and a more accurate way to input pitch, amplitude, and the amplitude of each polynomial. Enjoy
