Hi. I just noticed that the BD with the Extra9 mod in fact does have a hiss, which I cannot seem to alter while turning the pots on the front panel. You can have a listen to it here: https://gofile.io/d/W1363v Is this the same behavior you were experiencing on your unit? Thanks, F. Not sure if it i...

I finally found the issue. This post helped me. In the Bassdrum section, cable 1 and 2 (noise decay in/out) leading from the Nava to the Extra 9 board, must not be bundled with the other cables. There's indeed a crosstalk from noise to audio. Simply separating these two cables and keeping them 2cm a...

I just tried out a toroidal transformer, 15VAC 2.667A. On load (Nava on and playing a pattern) I measure 18VAC @ 970mA.

But still the same hissing on the BD decay. Gonna have to find something else.

Finally I recall I had this. I probed the + and - 15v and found they had the small oscillation we hear on the bass drum. I could also hear it on the steiner parker filter. Thanks Gihaume. I guess I'll have to play with another power supply. Maybe simply use a toroidal transformer instead of a wall ...

Could it be this ? Thanks, Gihaume. I'm currently unable to check my power supply (it is installed somewhere deep behind a rack). But I recall reading this thread, when I was building the Nava. So I'm pretty sure I took a power supply with >= 1A. But I indeed have a little bit of distortion on the ...

My Nava has a noise floor in the decay phase of the bassdrum. I've recorded a .wav file here: https://florianmoser.ch/909-noise-decay.wav

It is recorded right out of the BD-output, but the noise is also there on the mix-output.

Does anyone else have this issue?

That's what I thought. Looks nice, their products. Let me know if the timing is good. Might get one as well

flomo

Thanks, orbist. So now I know its a feature, not a bug, that's a great start

Will check out that 64pixels stuff.

I have a TB-303 attached to the Nava DIN Sync port. When the Nava is configured as master, the timing is perfect. However, when I set the Nava to slave mode and sync it to MIDI, the DIN Sync out clock is quite random and unsteady.

Any ideas how to solve this?

On some of mine, the caps touched the switch and jammed, when pressed down fully. So what I did was inserting some pre-cut pieces of plastic (from a blister package) into the shaft of the caps, so that they don't go all the way down when being fully pressed. In short, I increased the distance betwee...
