 positionhigh | You need to set only the midi pins to type a or type B and the amp to be present or skipped. Everything else is for very specific needs | 21:08:36 |
 m.c.gentry_31770 | ok great, thanks | 21:10:12 |
| m.c.gentry_31770 | what about Chase Bliss MIDI Z? JK, those guys are krazy and their MIDI is all to itself | 21:11:01 |
| positionhigh | What is this, like a midi effect pedal ? | 21:14:30 |
| m.c.gentry_31770 | Chase Bliss has a bunch of pedals and they use TRS MIDI. However, they don't use TRS A or B, the use their own set up where signal flow is only on the ring. | 21:18:15 |

| m.c.gentry_31770 | I'm building a (2nd) MIDI pedal controller now that will have a Teensy, USB and TRS A and B connections, but not ChaseB. I'll just make a cable for that | 21:20:01 |
| m.c.gentry_31770 | yeah, definitely | 21:22:23 |
| m.c.gentry_31770 | MDT ain't a MIDI controller | 21:22:26 |
| m.c.gentry_31770 | (honestly I'm not sure what to call it! Box that Makes Music) | 21:23:15 |

 .ragrat | OK, so I've got my PCBs and I have mostly populated one. Still got to work out how to connect my MIDI DIN sockets (doing a bigger case so I can fit things like DINs, batteries and a 3.2" screen) but that's tomorrows trick so now I feel ready to ask this. What's the story with the oscilloscope? Is it only mine that never shows a wave amplitude that exceeds a couple of pixels? Seems like a bit of a waste of resources although that flicker is useful for troubleshooting. Even if you can't hear anything you have a flicker of activity and it tells me something is going on. It would be nice to have it working but it would be best used for visualizations while programming the synths I would have thought. | 11:04:14 |

| positionhigh | It is much stronger when the multi band compressor is in use. | 11:16:59 |
| .ragrat | That turned it off leaving a much shorter non-moving line to the left of that area maybe 4mm long. | 11:26:36 |

| cfors | MDT EUROACK Yes, it works!!! some small adjustments, some connections to make (MIDI IN - MIDI OUT), SD card, screen calibration, which I will do in the next few days. In the meantime, I'm already happy like this! | 00:59:44 |
 lummsmusik | Maybe it was still ask anywhere, sorry 🙂. But I recognise a permanently high pitch beep when using my MDT. Is there any easy solution to avoid this kind of problem? | 10:03:48 |
| positionhigh | lummsmusik it should not do that, are you doing anything special like an other DAC ? | 11:50:24 |
| positionhigh | cfors the capacitive touch does not need any calibration. Or is it resistive ? | 11:53:23 |
| lummsmusik | No, DAC as in the BOM. Maybe I try a different USB. Some similar problems I solved with using a powerbank rather than an USB hub. | 16:16:05 |
| cfors | positionhigh I didn't have another Teensy 4.1 to program for the capacitive screen, just to see if it would turn on and work I tried using the Teensy that I had programmed for the resistive one... obviously it worked badly, today I programmed the new teensy with the right one firmware and everything works perfectly! Thank you 1000 for your magnificent work!!
P.S. the OPA1622 output buffer that I used as a second order filter for the DAC and as a headphone amplifier works very well, maybe try it in a future version. | 19:27:47 |
| positionhigh | cfors thanks for that suggestion, I will look into it but might to learn a bit more to use it I think | 20:03:59 |
| positionhigh | lummsmusik most noise comes from the power source. However the pcm5102 should have no audible noise of any kind. | 20:06:31 |
| .ragrat | I've been calling mint the freak box. | 23:37:25 |
| .ragrat | * I've been calling mine the freak box. | 23:37:41 |
| .ragrat | * I've been calling mine "freak box" for sequencing etc. | 23:39:25 |
| .ragrat | Is it only me that has a broken MIDI? The MicroDexed locks up to various degrees after a certain amount of activity on the MIDI input port. Is it something that I should be going nuts over with my assembly of the PCB or is it a known bug? Seems to have been a thing since I started with the capacitive touch screen but I assumed it was a bit of breadboard slop with the connections. Still there with the hard wired version though. | 23:44:31 |

| positionhigh | Are there custom samples from spi flash involved ? | 11:19:08 |
| lummsmusik | Attention! Someone could mismatch it with the freaq fm by wirehead 😉 | 12:31:25 |
