  1. @dwestbury Vice/vsid runs stable and well on Windows (also as a x64 build). Do you currently have a Sidplay build for the mac version with ASID support at hand, which will also run on the latest macOS versions (maybe Arm64 Silikon support)? I can try to compile it according to your description...
  2. Ok. 3387 ist the one, which is used in 1st Waldorf 4-pole Revision.
  3. Are you looking for CEM 3387 or CEM 3378? Both differ in certain functionality. Yes, it is rare, but not impossible to get. Wait and watch on ebay or second hand sellers, etc. the price should be double (or even higher) what it was 20 years ago. e.g. the cem3378 were rare even then. I got mine (3378) around ~2006 for 20 euros each. But those were already the last in stock. Greetings, rio
  4. Do you have experience in programming? The reason I ask is because it requires that. And your approach of changing the args of a core function is definitely not the right way. Btw: I think this is pretty custom for your needs, since the mute works in a different way in the midi implementation (regarding tracks). Otherwise, if you absolutely need it and above all if you are confident that you can do it, then you can hack the seqv4 source and define and include your own external control as a CC and specify & transmit the channel there as a value, which is used in your own loop through the tracks and mutes or unmutes the corresponding tracks if (value == track's channel). e.g. seq_midi_in.h --> #define SEQ_MIDI_IN_EXT_CTRL_MUTE_BY_CHANNEL 16 #define SEQ_MIDI_IN_EXT_CTRL_NUM_IX_CC 17 <-- (make sure to increase the NUM_IX_CC) seq_midi_in.c --> seq_midi_in_ext_ctrl_asg[SEQ_MIDI_IN_EXT_CTRL_MUTE_BY_CHANNEL] = 122; // your cc for that control const char* ext_ctrl_str[SEQ_MIDI_IN_EXT_CTRL_NUM] = { .. "Mute by channel", // your name for that control } <-- (index 16 must be noted here) append your external control handling inside: static s32 SEQ_MIDI_IN_Receive_ExtCtrlCC(u8 cc, u8 value) if (cc == seq_midi_in_ext_ctrl_asg[SEQ_MIDI_IN_EXT_CTRL_MUTE_BY_CHANNEL]) { ... } but i think if you want to change something in the code, you have to get familiar with the structure of the entire source anyway. Greetings,rio
  5. It reads a little heavy but can you briefly describe what exactly you want to do? Do you want to mute all tracks that listen to a specific channel?
  6. This should rather be opened in a separate post.
  7. this fix refers to the following issue (midibox seq v4 release feedback): The quantized recording loses its sustain (GLD) due to the offset of the next step, since the note of the step to be played is not passed and the recording loses the (note/sustain) information in the next step. seq_core.c: 1. replace this line: https://github.com/midibox/mios32/blob/master/apps/sequencers/midibox_seq_v4/core/seq_core.c#L1053 with: if (SEQ_RECORD_NewStep(track, prev_step, t->step, bpm_tick)) mute_this_step = 1; mute or not to mute? thats the question! seq_record.c: 2. insert this code: if (t->state.REC_DONT_OVERWRITE_NEXT_STEP) { int next_step = new_step + 1; // tmp. variable used for u8 -> u32 conversion to handle 256 steps properly if( next_step > tcc->length ) next_step = tcc->loop; new_step = next_step; } before: https://github.com/midibox/mios32/blob/master/apps/sequencers/midibox_seq_v4/core/seq_record.c#L727 3. replace this line: https://github.com/midibox/mios32/blob/master/apps/sequencers/midibox_seq_v4/core/seq_record.c#L735 with: if( any_note_played ) { which also passes flagged REC_DONT_OVERWRITE_NEXT_STEP. 4. replace this line: https://github.com/midibox/mios32/blob/master/apps/sequencers/midibox_seq_v4/core/seq_record.c#L843 with: return any_note_played; // no error instead of no error code, but it is enough that it is returned positive. Note: It is more of a hack than a concrete fix (it only works for tracks that are played forward), but for my purposes it works - if you actually like to use the quantization feature for live recording. But your desire to get an "undelayed, unquantized recording" has nothing to do with this solution. This hack is suitable for a working quantization during live recording of tracks that already contain & process midi data. Maybe quantization can give better results when recording notes, except that it does not conflict anymore with existing (already recorded) data in my modification.
  8. Hello steve, Is it possible for you to make your own binary from the sources? I have written a fix for quantized live recording in the past... you could try the code changes/snippets which it affects. Let me know if you would like to try it out. Oh, you mean a possibility of an exact "unquantised recording". Of course, my suggestion doesn't fit there. greetings, rio
  9. yes, the PIC18F4620 is the core for the SEQv3, but as already mentioned, the SEQv4/v4+ goes a lot further (SD Card instead of EEPROM support, the source code is mostly written in C++ instead of ASM etc.). DINX4, DOUTx4, on the other hand, are compatible.
  10. fine If you end up uploading the Midibox SEQ app via midi, you should be able to manage sessions from the midibox options menu. You do not need to make sessions via the terminal - but it is possible. If you have the feeling that something in your 'old' session is stored incorrectly or is corrupt, then you can also try to load this session and copy certain things (patterns etc.) into your new (cleanly created) session - all this directly on the unit. And maybe in future just make a backup of the SD more often. no corrupt files have happened to me in all that time, but I always make chronological backups on the PC. That's tooo long! So my suggestion: please test a new SD Card <= 4GB! I also had problems in the past with SD cards of different types. Maybe my old thread helps out (but note, I use a LPC17 core - but the conclusion is to use a smaller SD card, which I have already mentioned): Perhaps as a tip for the future: I can't say anything about the hardware problems, but you should also check all the connections to the SD card - in case you soldered together your own SD card board (or the previous owner). Otherwise, test another SD card).
  11. You should backup these files as long as they can be read on the PC.
  12. I never said it shouldn’t be a hardware link. Maybe the right term is „debug Interface“, … …but I don’t have STM32F4 in use for my mbseq.
  13. I don‘t think, that you have care about a SD card for uploading mios32 app or (in the worst case) flashing bootloader by a linker.
  14. This is a standard message when the bootloader/mios32 is on. It is good that it is running. After that, you can safely upload the MBSEQ, but for the right core! - which is not quite clear here yet (probably STM32 core).. but MIOS Studio should already give you the info back with the USB midi connection. more infos here: http://www.ucapps.de/mios32_bootstrap_newbies.html and here: http://www.ucapps.de/index.html?page=mios32_bootstrap_newbies.html Mios Studio 2: http://www.ucapps.de/index.html?page=mios32_bootstrap_newbies.html
