  1. midiphy SEQ v4+

    Yess, me too! A while ago I bought a set of keycaps from Antichambre for my LoopA and I regret I didn't order them for the sequencer, these were the last spares...and I love them. Would be great if we could order them from the webshop. 
  2. C3 with diff vel. 2 diff. notes

    Hi, it's been a while, but I'm still busy with this project. Till now I just used ableton to trigger the solenoinds through the midio128V3 box. But now I want to play them directly from the midifile on the midio128box. I don't know where to put the piece of code bruno gave me. I copied it in the app.c file and that works for the midi input of the midio128box. But, as Bruno said, it doen't work for the midifiles on the SD Card. I tried different things with routing, but I can't seem to route the midi events from the midifile to the midi input of the midio128box. So I looked further  in the "src" folder of the Midio128V3 app, that's where the app.c file is, and there are lots of other files. I copied it to seq.c, It complise but with no result. And I copied it to the mid_file.c, but that I can't compile cause "midi_package" is undeclared in this function. I hope someone can give me some extra hints cause now I'm stuck again. Thanx!

    Hi Thorsten,  Thanx very much for the fast reply, I'm sorry I'm not that fast.... But I think the Hz/V calibration works like it should now, although you really need a unipolar CV output. And I didn't notice any difference in the calibration procedure but maybe you just changed the code and not the procedure?!.... The renaming (Aout > CV 1t/m4) and the GP7 uni/bi polardisplay button is indeed more convenient and looking good! I didn't remove the resistors yet, but I measured the following after the Hz/V calibration: C2 on the sequencer gave me -1V,  E2=0V,  C3=3V,  E3=5V .   If I add 5 volt to this (changing from bipolar to unipolar) C2=4V,  E2=5V and C3=8V and that's is exactly what it should be so that's why I think the calibration is correct. It is so confusing cause the CV input range of the ms20 is from 0 to 8 Volts, so the ms20 starts playing on E2/0V, and the highest reachable note in bipolar mode is only 1 octave higher E3/5V, and within this octave the ms20 jumps through 4 octaves. That's the difference between lineair and exponential, I was never good at this stuff, I hope you people understand me... Thanks again for all the help and the new release, looks very promissing, 4 CV modules is superb and track labeling and all other stuff is just great.

      I will!, and I'm not on a hurry so if it isn't tomorrow, no problemo, thanks anyway!

    After calibration I got as close as 0.998V 1,997V....9,999V, so that seems working reallly good. I didn't check the manual, but I've been using my ms-20 for over 20 years, and have been using it with different midi2CV converters and always needed to select V/Hz instead of V/Oct. I also used it on my 'old' SeqV4 with build in Aout board and that always worked good with the Hz/V setting in the CV configuration.  There is a workaround for using V/Oct on a Ms-20. You put the bi-polar CV signal into the Ext Freq input, and turn the corresponding pot to around 9 'o clock. But it's quite hard to get a good stable tuning over multiple octaves this way. I'll try to remove the resistor and make a unipolar output and see what that does. If it's only offsetting the CV value I can't imagine that it will scale alright, but I'll try and let you know

    Hi, last week I finished my eurorack modules and they seem to work fine now. At first they (clocks and gates) started normal but after a few seconds they started to add randomness. In the end I found out I hadn't soldered the db25 connector to the board,.. stupid! The calibration feature works really nice and handy!!! I managed to get a good tracking over at least 7 octaves on my sh101. But.... When I switch to Hz/Volt, for controlling my korg ms-20 I get a really strange output, I get the complete range of 4 octaves under 1 octave of my keyboard. Am I missing something, does the Hz/V has its own calibration, or isn't Hz/V implemented yet?!  
  7. Wow, looks beautiful! I just finished the eurorackmodules, will start on LoopA one of these days

  9. C3 with diff vel. 2 diff. notes

    Hi Bruno, Thank you very much! Altough this is quite "abracadabra" to me, I managed to copy your example in the app.c file of the MIDIO128_v3 folder and after some troubleshooting it recompiled, and it works! I can play C3's with different velocities and they're played by DOUTpin 0,1 and 2. I'll manage to expand this further to my needs. Only thing I'm a bit worried about, is that I just add a bit of code to the MIDIO128 app, and that this piece of code will "struggle" with the original app. Or shouln't this be a problem?! Thanks anyway, I'm ways further to my goal now. HERE is an early vid of my experiments
  10. C3 with diff vel. 2 diff. notes

    Hi, I'm building a midi triggered snaredrum with solenoids controlled by a relay board wich is controlled by a stmf4 running MIDIO128 V3. To get some sort of velocity control I want to use different solenoids, micro's, 5N  and 20N strength. So when for example, C3, velocity 64 is played it will activate DOUT pin D01, and when C3, velocity 96 is played it will trigger DOUT pin D02 and when C3, velocity 127 is played it will trigger DOUT pin D03. I hope someone can point me in the right direction how to achieve this. If someone knows how to do it in Ableton, change C3, velo 65 to C#3 for example then that would be cool too. I make midifiles in ableton and let them play by MIDIO128 Thanx

    Yess, that would be nice, I'm always wondering where my sounds come from!

    wowie I like it more than expected, looking good!
  13. midiphy SEQ v4+

    I'm interested,... but the LED window is way to small for me. So I don't think this is an option for me, although I understand the feeling about the shining through the neighbour knobs. Last weekend I did my first gig with the sequencer, There was a lot of smoke, lasers and other flashing lights and I totally loved the big coloured buttons, it felt very sturdy/secure! So obvious what you are doing :)...
  14. Hi, I just tested it on a windows10 64bit with SeqV4+ and it seems to work very good/fast. But when using MIOS File Browser I still get the "Invalid response from MIOS core during read operation" when I try to download the MBSEQ_HW.V4 file.. But with my new machine I can easily pull out the SD Card so no troubles for me. On my previous Seq I glued the SD Card inside and couldn't reach it anymore. Only by making it an external Disk and then I only was able to upload the Seq firmware again through my GM5x5x5 to the Seq. Thanx fotr the update!
  15. He Electrodancer,


    I'm interested in your midibox stuff, oh en ik ben gesitueerd in Nederland, dus das lekker makkelijk. Als je mij een paypal betaalverzoek doet betaal ik zo snel mogelijk. Ik kan het nu ff niet gewoon overmaken aangezien mijn rekening bijna leeg is, paypal gaat via mijn creditcard...
