Teensy 3.2 is fine. Last ones I bought were from Mouser.

I seem to have just fried my second Radio Music. Was removing it from the rack while powered up so I could adjust the trimmer to reduce gain and distortion. When I put it back, I must have shorted some pins against the adjacent module's faceplate - it's dead now.

I removed the Teensy and TL074 and did the voltage tests. Zero voltage anywhere. Suggests I have blown something in the power supply. Any suggestions what to replace?
Maybe try L1 and L2...
I doubt that the ferrite beads or resistors would have blown, especially seeing that there are two reset-able fuses. Try swapping out the teensy with the "other" Radio Music.
I meant the fuses as well... But in the schematics it is very unclear what the fuses are called (they are not named at all). So I mistakenly thought they where called Lx...
:doh: Sorry for that!

Follow up question: Does it have to be a teensy 3.1? Don't seem to be many around now. 3.2 or later.
I have a 3.2 in mine. I think the only difference between 3.1 and 3.2 is that the 3.2 have a beefed up on-board regulator so it can drive more hardware off its 3.3V regulator.
Thanks!

Is anyone working on a higher fidelity version of Radio Music?

It does so much of what I want that other sample players literally can't, but the noise floor really restricts what kind of sounds I can use it with.

hey wigglers

I just built a radio music (chord organ actually) and I`m wondering if people still strap a 100k resistor in parallel to C4 as mentioned here:
https://github.com/TomWhitwell/RadioMusic/issues/70

i have red rev 2 pcb from thonk. I couldn't quite figure out if this is still needed or not.
can anybody help me with some insight on this ?

Does anyone has this issue still? I got a new Radio Music with Teensy 3.2 but cannot get any decent sample out of it. At least not with firmware 7.x
Older firmware seems to work but these don't support wav files etc.

Apologies for the super basic question. When a piece of audio loops back around, is this completely smooth/no click? I've read about fade in/out and de-click functionality. Any difference on short versus longer files?

I have read the manual and have watched a few videos, so I think the answer is yes, but just want to be sure ;)

is there any mod or module to have radio music with a pitch option on current playing sample?

(I know the pitch update config but I mean another knob or something that can keep start position knob)

Is there any Tiptop One versus Radio Thing discussion on the site? Or if anyone wants to chime in here. I've researched both modules, alternative firmwares is definitely sweet, but as I would get one of these modules for sample playback, sound quality might be a concern. The One can be used for CV as well, but not sure I need that. Low latency trigger is also useful on the One, but again, not a dealbreaker at the minute. In my current setup I would be using it to input audio into Clouds (Monsoon) and Rings.

I have both, One is better for the very low latency, pitchshifting quality and integrated level control. RM is better for the file navigation with banks it's easier to find the file you need.

Regarding the B50k pots (TIME_POT and CHANNEL_POT)....do they strictly need to be 50k? I could be misunderstanding, but it doesn't seem like the pot value should really matter. I have a bunch of B10k pots, but Thonk is out of the B50k ones.

I heard from Tom at MusicThing, and according to him other values should be fine, so long as the pots are linear.

I bought a second hand Radio Music recently and it seems to have an issue with the station knob. If it is anywhere from CCW to approx 2pm I think it is constantly retriggering as the reset light flickers all the time. Past 2pm or so it operates fine, no noticeable problems.

Can anyone suggest what I need to look at to try and solve this? Is it a wonky pot maybe? I'm not a particularly experienced builder although I have built a handful of kits and I'm not really sure what to do.

Would be so nice if it was possible to have a mode where we could both pitch and address position in the sample - are there any alternative firmwares out there?

Please let us know how the 10k pots worked for you. I'm also running out of 50ks...
The GitHub says : "Previously it was stated that using 100k pots is ok, but it was found in testing that this could lead to CV instability."

Everything seems to work just fine on mine with the B10k pots :tu: Dope little module!

I took a brief look at it some time ago and thought the cleanest way would be to wire up one of the unused ports on the Teensy and then modify the firmware to read/use that port in addition to the current one. I have a 5U version, so I'd have room on the panel for an additional pot and jack.

About the only thing I don't have is a lot of time to look further into it.

For me Id be happy to just switch station cv to pitch cv and keep station only on the knob. That way its hopefully something that could be done in firmware without modifying the hardware. I dont have the coding skills unfortunately :waah:

That was going to be the first thing I tried as a proof of concept. Really, just need a few days of uninterrupted time to look at it. That's in short supply at the moment though.
