  1. Awesome...I'll start there - thanks for the fast reply!
  2. Hi Andy and Peter - Got a weird bit of behavior from encoder #9 and looking to see what your recommended steps to diagnose would be. The encoder is showing some weird behavior - pressing it works and registers, turning it while it's pressed registers, but just regular turning it doesn't work. Sometimes after I press it it works a little bit like it's skipping around but mostly it's dead unless I'm holding it down and turning it at the same time. Encoder went bad do you think? Thank you
  3. Hmm..that is good to know. Could be my somewhat modern gear - although the SL Mk2 is pretty old I think. Thanks
  4. For some instruments with Midi DIN I have, but shouldn't I at least see some activity on the midi monitor under USB1, USB2, USB3, or USB4 using a usb keyboard?
  5. That is awesome progress/news on the cv modules, very cool stuff! Got a quick question that I guess is more troubleshooting related than operation related - On the Midi IN4 and OUT4, I know they are planned for controlling the BLM at some point in the future, but in the meantime should they work as regular Midi in/out ports? I have a keystep plugged in and it works on IN1, IN2, and IN3, but not 4 (when viewing via midi monitor). Was curious if it's a midiseq software setting or intentionally hardwired to be different. My vote goes to bad wiring on my part, but just double checking. Thanks EDIT - Actually the more I read on the USB OTG it seems like I should be able to plug the keystep into USB with the switch in the OTG position. Quick power cycle but still no activity on the midi monitor. The same if I try with my Novation SL MK2 midi keyboard. Both they keystep and SL are being powered by a PSU and not reliant on USB power. Do you need a special OTG cable for it to work?
  6. Many thanks, Peter. I got a deal on 8580s from meeblip awhile back, I'm working through PSU option E. Got an OLED screen. I'm thinking of panel mounting the switches directly above the window so I can flush-mount the screen. Probably just build my own enclosure, it looks pretty cramped in the PT-10 and I like a little more room to work with. Based on your one post about how much of a pain the flat leds are I'm thinking of just going with regular round ones. The PSU is tricky for me since Jaytee's build guide leaves off necessary components from the original Wilba build guide, which makes sense since its original intention was a retrofit but a little confusing for scratch builds. I think I can figure it out.
  7. Lucky 13! Thanks, @Hawkeye!
  8. All working now - Here's my beauty Turns out I had a bad cable (my nemesis) for the MIDI8 board. I went with the red/cyan color mix for the LEDs. Keycaps courtesy of @Antichambre . Also, I went with shorter 16mm keycaps for the switches ( mouser 642-1S11-16.0 ) instead of the 19mm from the BOM, I thought those were a bit too wiggly. I had a few self-inflicted hiccups along the way but I'm extremely pleased with how this turned out and the quality and support of the midiphy kit is top notch, of course. Cheers!
  9. You wrote this kind of a long time ago @Hawkeye but can I ask why did everyone used JB-Weld in the first place vs just having screws from the top? People didn't want to see the screw heads on top of the panel? Why not use the encoders to attach the front panel? Looks like there is room to lower the panel a few mm - was the height dictated by the original LCD height? Apart from the flat-top LEDs being a bit of a pain, anything anyone would do differently with their build? I've read all the big threads and really studied the wiki pages. Looks like an exciting project!
  10. Latigid on and Hawkeye - THANK YOU! It's up and running! (one caveat below...) Sorted out my JA board issues and it's firing a basic sequence now. The OLED displays are amazingly crisp and clear. This box is a thing of beauty, really quite a nice piece of engineering and design. I am looking forward to learning it. Thank you for offering it as a kit! One caveat, though (there's always one in my world), is that I'm getting weird output from the 4 main Midi out ports. To test it I'm running a simple sequence with one note and one default gate length, and my synth gets the note (a behringer neutron) but only once ever, and it's like an infinite gate. Happens with all 4 of the Midi out ports. The IIC ports all work great when I change the midi output port on the fly while the same sequence is still running. The IIC ports appear to be operating normally so I'm thinking it's an issue with the midi8 board. Before I tear it apart and examine the midi8 pcb, I just wanted to confirm that there's no global setting or something that I need to enable or set for midi8 board? I'm guessing no but hey just double checking. If I do need to debug midi data, is there a recommended method or test sequence I should run against a known good port? Should I use mios studio or midi-ox or probably doesn't matter? Thanks again
  11. Just reporting back in quick - it was the cable. I guess practice makes perfect, now the led matrix works perfectly. Getting there :)
  12. @SimonSays Please keep us updated since I also ordered the PCBs from modular addict awhile back. I'm hopefully finishing up my seq v4+ build soon and will tackle a 6582 build soon after. Got a small bonus at work and splurged on a slew of 8580 chips from meeblip a few months ago in preparation, also. I guess they are sold out now. Have you turned up any ideas for the display? The hot thing is OLEDs now and some people get them to work it appears, though I haven't found a real guide.
  13. Thanks - I think it's the cable. I have continuity everywhere but from J5 pin 8-> cable-> j2 pin8. Will replace that once I get new ends - I think I wore out the 24pin header.
  14. Hi - I had some more time today to make some really good progress. So far everything is going smooth except for the JA board. I have the case almost all the way together. for the JA, I'm going to debug the weird button behavior I had way back, now that I know how the ICs work a little more. Anyway do you know what would cause this row not to light in the matrix (please see photo below)? The 2nd row of 16 leds aren't lighting on the JA matrix. I've reflowed the matrix pins and the large 24pin connector, as well as the respective connectors on lemec_r. I am guessing this matrix doesn't connect to anything else on the JA board that would cause just this row to not light? Thanks
  15. Makes sense, I suppose it would want to go as fast as possible for quick registering. Is the RC = reset clock? Still not seeing any action on switches. I did for a little time right after I reflowed the ICs I mentioned but now nothing is showing up in MIOS. I'll test all the pins again with the scope and report back and basically go back through your previous posts on this thread. I still get perfect encoder twisting registering in MIOS studio, just no switches.
