I have the layout as per your first diagram. Changing to the second one, i.e. connecting the AlphaTrack to a monitor object, did not fix the problem. I was still getting notes ON to the MBCV. When connecting the MBSID to a monitor object I was able to remedy the situation. This means that somehow MBSID sends events that are interpreted in Logic and sent out to the selected track. I guess I will probably have to stay with this current workaround as I am not using MIDI OUT from MBSID. I would also recommend some guards in MBCV against stuck notes as it might happen in other situations as well. Many thanks!

I am not sure changing the midi channel will solve it as it will happen for every highlighted track in Logic. Changing the patch change setting might not do the trick as MBCV is getting notes ON without Off and not patch change.

Well, it is something in the interaction of MBSID and the Alphatrack. Only when clicking the STOP buttn on the AlphaTrack am I able to reproduce it. The STOP event, coupled by a program change to MBSID has MBSID 3 sysex messages that somehow are transformed into Notes ON and OFF that are sent out to the selected track. I am not sure which part of the sequencer chain does this transformation. Perhaps it is the Alpha Track device driver. When removing the MIDI OUT cable from MBSID, the problem does not happen, meaning it is something that MBSID sends. Is there a way to guard against playing a NOTE ON upon NOTE OFF in MBCV?

TK, It is a little complicated to arrange a midi file as it happens when hitting the STOP button. I have now managed to produce the following MIDI stream in the IN of the MBCV. It is evident that there are notes ON in the beginning without the notes off. I had created a new Logic song with two tracks, one is a MBCV and the other is a MIDIBOX SID track. I had added a one measure pattern to the MBSID track with one program change event. WHen the cursor is on the MBCV track, clicking the STOP button transmits the program change to the MBSID and then spits back the following MIDI notes: *** ZERO *** To MIDI Port Note On 2 C6 96 *** ZERO *** To MIDI Port Note On 2 G#0 64 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 *** ZERO *** To MIDI Port Note Off 2 C-2 0 After that, there is a hanging note in MBCV as per the above two MIDI notes without NOTE OFF events.

Hi, Well, it happens even if I just press the STOP button on my alpha track, which produces: 23:28:20.701 From AlphaTrack Note On 1 A5 127 23:28:20.861 From AlphaTrack Note Off 1 A5 0 23:28:20.900 From Port 1 SysEx Otari 266 bytes 23:28:20.985 From Port 1 SysEx Otari 266 bytes 23:28:21.071 From Port 1 SysEx Otari 266 bytes Note that I have Logic focuses on the track, which sends to the MBCV the above stream. Alpha track created a note on and note off with correct values. the sysex is from the SIDBox. Clicking STOP 3 times in a row creates that stuck note, probably the A5.... [EDIT: no, its note an A5, its more like a note from the Seq3, one that was played)

Hi TK, creating the pattern with the 128 notes, playing it back released the stuck note. Strangely enough, while walking by way up from C-2 and hearing the stuck note each time I entered a new one, when I had hit the problematic note (I think it was C2), the stuck note went the scale to around 7th octave. Finishing the 128 notes and playing the pattern, the stuck note is now released. I am using Seq3 latest firmware to play that sequenced part (1/8th note in 124 BPM). The chase command of Logic is also creating the problem as it chases the 128 notes of the first pattern (placed at the beggining to reset the sound) and creates a stuck note. BTW, is MONO mode appropriate for sequenced parts or should I go to another mode?

Hi, My MIDIBox CV is sometime producing a trigger with CV upon MIDI Note Off. When connected with a software sequencer, something is probably sent to the device (might be some controller, program change or another MIDI event) and after that, some of the channels produce a static tone upon MIDI Note Off. The only remedy is power off. Even program change via the encoder does not work.

As pattern change is optional and off by default, can we also regard bank change the same way? After all, I assume accidental pattern change will have the same effect as accidental bank change, from data loss I mean. If that could be added to the list, be it low priority, I would be grateful. The reason I am seeking this feature is my working method. I am not using the song mode as I keep restructuring my tracks in Logic, which forces me to move the song structure. Since the song is linear, it is a lot of work. I have opted to do pattern changes from Logic and control all pattern change that way. The only issue now is bank changes as those are not supported via MIDI. Thanks for considering this feature request.

Is there a MIDI control event that can switch a bankstick? I can easily change patterns in the four slots via MIDI but I could not find a bankstick bank change method via MIDI.

Hi, I am looking for a way to send variable GATE volume values based on the volume of the depressed key. This will in turn trigger ADSR modules with variable strength, in effect creating variable volume based on the key velocity. Whomper

anything that can be considered for a future software release?

I have a Seq3 that is serving both my normal hardware gear as well as my modular one via a CV converter. As I am now venturing into analog clocked modules (generators and slaved to external clock signal), I am in need to sync them both. is there a way to generate a modular CLOCK signal from a MIDI clock?

It seems like the gate signal level is a constant value and is not related to the incoming MIDI note velocity value. As such, my EG does not change level and change overall VCA volume based on incoming midi note velocity. If I could get the gate level to change based on incoming midi note vel, I could achieve the same dynamic playing as in the midi realm. Is there any way to change this behavior? Whomper

When running my Midibox CV with some sequence, the channel that is playing is stuck on the highest note (127) with the gate in open mode, and as the notes are coming in, it tries to play them in between it defaults to value 127 and an open gate mode. If I stop the sequencer, I hear the constant high note. If I change to a different channel, all is well for a random time until the problem manifests itself there as well. Only remedy is to restart the Midibox CV. Any clues as to how to resolve?

I have a Midibox CV and moving the detended control by a step (up or down) produces double events. Is it doable? Whomper

First, sorry about posting on this board, I could not find a Midibox CV usage board... When working in Mono mode for a channel, pressing and holding one key, and then pressing another key (while the first one is being held) does not produce a new Gate trigger. From my experience with Mono mode, each and every key press will trigger a new Gate event even if other keys are still being held. Is there some configuration I am missing?

well, by some miracle, things suddenly started to work. Whomper

I have made some more checks and it appears as if the TLV5630 does not produce any signal in all its lines. Might there be damage to the IC? Whomper

Hi, After succesfull usage of the AOUT_NG in my SEQ3, I have decided to go and build a MIDIBox CV with the NG. So, I have finally connected the AOUT_NG to my newly built CV box, only to find out I get no CV signal at all. I am testing +-15V in TL074 as well as 5V in TLV563. I get -1.195 in JP1 and -2.264 in JP2 and so on. Also, I have ~1.9V in pin 3 of the TLV563. In addition, resistors R33-R48 get hot while the +-15V is active. Any clues as to how to further debug this? Whomper

ok, still in need to build some more modules in modular before I can test it. I am building it piece by piece DIY style :-) On a side note and as for the SEQ, I understand it can serve the same purpose as the dedicated Midibox CV. I mean, I would like to both control the modular via SEQ as well as map incoming MIDI notes coming into SEQ to be converted as CV data into the modular. Is the above correct? How does this routing take place in the SEQ config? Can I also convert incoming MIDI controller data into CV? All via SEQ as a path through and MIDI to CV converter. Should I better connect the NG to a new CORE and build a Midibox CV instead which will allow me a dedicated MIDI2CV with proper administration UI? Whomper

Oh, missed the "DEFAULT_AOUT_MODULE_TYPE" flag. Set it up and I am getting voltage out of CV1, looking good. I will hook it up to the modular soon to test, but early signs are positive :-) Thanks! Whomper

Right, I hadn't noticed it was referencing the MBSID module connection... Well, I have connected it based on the SEQ-AOUT connection diagram, however I am getting no output at CV1 (testing with first CV first..) Any tips on isolating the issue? Whomper

Well, connected the NG to the Seq, voltage is as expected (I have used the 15V with 2K resistors option), but no signal is visible in the CV1 output. I have also noticed the pin connection's labels in the reference diagram (the one with the blue lines for connecting to the core) are not the same between NG and core. For example, NC:SC -> CORE:RC, NC:SI -> CORE:SC and NC:CS -> CORE:SI. Is there an error in the connection diagram? How can I verify all is well with the board? How can I verify CORE:J6 is outputting a correct signal? Whomper

Thanks for the prompt reply. I guess this is the recommended approach. As for current, how much does the circuit draw? I need to calculate current load on the modular PSU. Whomper

Well, just noticed I need a +-12V source for the aout_ng. What's the best course of action on this? Should I use the +-15V of my modular and step it down to +-12V? If so, which available solutions are available? (I am looking to avoid to use the 15V directly and change the board components at first stage). Thanks, Whomper
