PreenFM2 / Re: Multi USB inputs..

Oh yes !
USB OTG (switch between host and device) is very complicated.
In fact USB is complicated, which is why it's so simple to use.

haha, nice one!

PreenFM2 / Re: Edisyn Patch Editor for PreenFM2
« Last post by feijai on September 25, 2017, 10:27:02 PM »
The long-awaited Edisyn 11 is out, with patch editors for the Blofeld, Microwave II/XT/XTk, Matrix 1000, PreenFM2, Kawai K4, and Yamaha TX81Z.  Very extensive collection of patch exploration tools aimed directly at FM synthesizers such as the Preen.  It's a very major improvement over Version 10.  Please let me know if you find any bugs or problems.

support for usb-midi devices would be very nice indeed. Xavier, is this much work?

I like reading this thread.. This collaborative atmosphere, leading to an interesting improvement of the machine.. People having ideas, expectations, people having skills, people helping.. All this is a delight..

PreenFM2 / Re: reset to default, waveform .txt, arpgeggiator toggle?

About waveforms..
"Adventure Kid Waveforms (AKWF)

AKWF is a collection of one cycle waveforms sampled from various sources intended for use as oscillator shapes in samplers and synthesizers.

Length = 600 samples
Pitch = D1+2

You find them on-line at: http://www.adventurekid.se/AKRT"

600 samples per cycle is small, and is a good source of aliasing.. Maybe Audacity or any other wav editor can re-sample/filter them to 4096sample waves ??

But one has to remember that user waveforms are not saved with the preset.. Up to 6 user waveforms can be stored in the SF card, and then they are loaded when you power-on your Preenfm2..
If you make, for example,  a preset using userwaveform 1, and if you then delete or replace this userwaveform 1, then your preset will no more sound the same..

I don't know if anyone ever used any userwaveform for FMsynthesis, and I'm not sure that this feature is really imoprtant..

I can imagine you use the last algorythm ; 6 detuned carriers, each one using its own waveform, or all of them using the same waveform, and the individual envelopes would in fact make an evolving mix of them.. I would love this feature, but only with a bank of more than 6 userwaveforms, and filters, and filter envelopes.. In fact, a kind of Roland D20 or Ensoniq ESQ'1/SQ'80.. But that's not the purpose of the Preenfm2..
Have a nice time..

Oh.. I see.. I took the problem by the wrong side.. I was almost sure that Preenfm2 was class compliant.. But yes, now I remember that when I had just a kboard and the preenfm2 connected, without any computer, that was through MIDI and not USB..

there is a fundamental misunderstanding here.

the usb port on the back of the preenfm has no host facility, you can only plug the preenfm to a host (computer for example) you cannot connect keyboards or anything to it. if at all possible this would have to be added to the usb port inside the preenfm where the stick is inserted. support for usb-midi devices would be very nice indeed. Xavier, is this much work? (it would require usb hub support and usb-midi parsing)

PreenFM2 / Multi USB inputs..
« Last post by opus.quatre on September 23, 2017, 12:02:03 PM »
Hello there..

Been documenting on TEControl products, mainly for breath controllers..
They need a class compliant device, and I believe that Preefm2 is..
I mean, I believe that I would just have to plug the Breath Controller into the Preenfm2 and blow, and the device would sent its CC2 values and Preenfm2 would understand them, and obey..
The Pedal controller seems an interesting device too..
http://www.tecontrol.se/products

The thing is : If I plug the TEControl module into my preenfm2's USB socket, then I have no more USB socket to plug a Kboard into.. I can still use a MIDI DIN input, sure..

But is there a way to have 2, 3 or even 459 USB sockets to control the Preenfm2 ?? You know, for example, those cards we use on computers which multiply a single USB socket into 4 sockets ?? Probably not, as I suppose they need a piece of software to manage them..

Enjoy breathing..

PreenFM2 / Re: 2 filters in parallel
« Last post by opus.quatre on September 23, 2017, 11:01:01 AM »
Hi again Lokki and Xavier and the rest of the world..

Concerning the existing filter, and especially in "bandpass" mode, I believe it would be very good to have a "direct volume", or "dry volume" control.. Or a balance "dry/wet" so that we could mix part . well why should I explain, you understood why..

When I use the FMsynth on Caustic, with an electric piano preset, I often add one or more "multifilter" in "Band Isolate" mode, which is a band pass+dry filter, the "Gain" button being in fact a mixer/balance..

The filter in Preenfm2 is a presently 3 parameter module, so there is one vacant place on the display, and one vacant encoder, which could be used for this purpose..

Have a nice day..
Thierry

PreenFM2 / Re: custom extended firmware
« Last post by opus.quatre on September 23, 2017, 10:40:57 AM »
Hello @Lokki..
And hello @Xavier..
ANd hello @Everyoneelse..

First of all : a big thanx for the "hertz" detune which, I believe, should be an option available on each single synth.. Nothing more boring that a 4hz "beating" in the upper octave when the ensemble effect in the lower one is so slow and sweet..
I think that, using the mattrix, it was still possible to use Note Scaling as source, OpFreq as destination, and a negative value (-0.0001 ???) if the detune is >0, and vice versa, but that means  using up to 5 matrix slots, and some time to set all this up.. And that would waste the Note Scaling which can be useful for envelope rates or Modulation Indexes..
This HZ function will be more versatile, lighter, easier to use, less dispendious.. If I'm allowed to vote, I would vote for Xavier including this function/option in the official firmware..

Second : Usercc is probably an useful feature too.. I can't tell for the 2 other new features, as I don't understand much what they are and what they mean.. I need more experience..

Third and last : Autumn is here.. Enjoy it..
Thierry
