preenfm2 and preenfm3 / Re: [done in v0.100] PreenFM3 QoL Suggestion

« on: December 20, 2020, 11:49:07 AM »

I must admit when I read the suggestion, I didn't really think that making the bottom row of buttons select the OP would be that big a deal. But now that it's there, it has made navigation noticeably smoother. Nice one.

preenfm2 and preenfm3 / [solved in v0.100] midi cc#31- feedback

« on: December 13, 2020, 06:29:04 AM »

Hi

Does 0.99b have the feedback controllable by midi CC#31?

Does this refer to the feedback value in the MI menu?

I can't get it to respond. Other CC's are responding as expected. I've checked in both MI 1 and 2 menus.

Could the feedback parameter be made a destination of the matrix?

Thanks

Helpful as always, thanks @served

I have emailed you about this to discuss further.

Just had 5 TFT crashes in an hour so it is still an issue. And ignore what I said about only happening on the Preset loading screen- it's happening in editing screens now too.

Ran the full 'TFT stress test' that you made as per the wiki.

Using the same 9v adaptor, again got the magic number 0.

Awesome work Xavier, troubleshooter extraordinaire! 

UPDATE: had a longer session last night, about 3 hours. During that time the TFT blanked 3 times,
The auto re-init worked twice, I had to do Menu Inst- button press for one.

EDIT- this part is incorrect after further testing (see below): each time was when I was in the Preset load screen.

Still a vast improvement over what I was getting previously. All the same I think I'll just go back to the USB phone charger as I can't see any benefit to using a 9V adaptor?

0.99B

Just tested for 45 minutes with a different adaptor. It's centre negative but I used the polarity converter.
The 9V adaptor specs say:
INPUT 100-240V- 50/60Hz 0.3A
OUTPUT 9.0V=1.0A

Zero TFT inits! 

I'll run the test later too.

Hi Xavier

I have just stuck with using the phone charger to power the Preen over USB as it works perfectly.

I did pick up a polarity converter though, so I can try a couple of different 9V supplies and report back.

Sorry if I caused any confusion by mentioning 7.5V. The only reason I mentioned this is that the metal case (used by Ardi in his build) has printed above the power supply "7.5-9V DC". I'll ignore the "7.5V" part of that and just use 9V adaptors.

Thanks for the update too!

preenfm2 and preenfm3 / Re: super slow LFO?

« on: December 04, 2020, 07:32:18 AM »

No problems, it was just something I was playing around with. I realised I probably need to use an analog synth for what I wanted anyway, because the increments in IM amount (eg. 0.5 ->0.6) are too noticeable in digital.

The OT can send pretty slow LFO over MIDI so I used that.

« on: December 04, 2020, 04:25:16 AM »

It's a nice suggestion. I gave it a try and it gives the same result as just setting the LFO frequency to .01 (I didn't time it but it seemed like about the same length of time). I'm wondering about even longer cycles to make reeaaaallly slow changes to the IM indexes.

I'll try doing it via external MIDI control, but I was just curious if it's possible to do with the FM3 alone.

preenfm2 and preenfm3 / super slow LFO?

« on: December 03, 2020, 07:37:41 PM »

Hi Xavier

Would there be any way to have the option to make LFO rates really really slow- like one cycle takes 5, or 10, minutes, or  even longer?

I don't know what the technical limitations of this are so maybe it isn't possible? Or maybe there is already a way to do this I haven't found?

The option to select usr wavefiles for LFOs' would be fun too.

Hi Ardi

Would this be an issue on the first batch of assembled units you made? What's the size of that plastic isolation washer (if we need to get one?)

Thanks

Re: power supplies- should we be using 7.5-9v dc with at least 1A (1000mA)? Any other specs to look for?

Power over USB (via a phone charger adaptor: 5v, 2A) seems solid. A good hour or so running with no TFT issues 

I can't find any other 9V centre positive AC adaptors in the house  to test (plenty of centre negative, of course)....

Any one else having TFT display problems with DC power?

Anyway, I'll just stick with the phone charger for now!

Do you know what volatge provides your AC/DC adaptor (by measuring it directly) ?
Some non-regulated adaptor provide more than the written 9V which could be a problem.

Can you try with USB power ?
(To know if that comes from the adaptor or the 9V->5V preenfm stage.)

Sorry I don't have a multimeter to measure the voltage.
I will try with different adaptors and USB power and report back.

0.98b.

Sorry Xavier- I really wanted to be able to report no or fewer problems, but there's no difference regarding TFT stability.
Just playing around with simple OP parameters, not even using the ARP or SEQ.
Seems to happen in any menu screen (I can't find a pattern to it).
Just MIDI notes via a keyboard on MIDI 5 pin.
