BLM functions

Hi. For working with the Seq4+: Where to access the ALT key (Switch octaves)? Shift+col16 doesnt work!.
Double tap on the track button should mute/unmute? No function too.

thanks for the report - looked into the code - it seems that TK. designed ALT to be only working on the virtual BLM interface, which had an extra button, that is not on the original BLM and not on MatriX, here’s a snipplet of the respective code section from SEQ v4+:

It might take a bit, but i’ll look into it - how we can get the ALT “virtual button” functionality working in MatriX, it should definitely be doable!

Best regards,
Peter

Strange, that nobody noticed the lack of this funktion yet. Especially cause it is mentioned it in the manual…
I don’t think, that pressing more than 2 buttons is very comfortable. What about using the sliders, as it is implemented in the Loopa mode.
Is therefore another way to change the octave in track or keyboard mode?
What about double clicking for muting tracks?
Another question: where to assign cc messages to the sliders? The manual reads seq v4+ option 30. Where may I find this numbered options?

1) Regarding mute/unmute, this already works, just push shift and press extra column key “3” or “4” to enter mute/unmute or solo mode as documented in the manual. Pressing any of the extra column keys then will just mute/unmute or solo that track as long as you are in that mode.

2) To assign CC numbers, go to the SEQ v4+ options page and scroll to option 30 - then you can assign CC# to all of the sliders (Menu -> Options -> Option #30 - Assign fader CC, then you can assign CC numbers to all available sliders)

3) Regarding ALT, yes, that is a bit strange, maybe not too many people (including myself) relied on the ALT functions yet, but it is now possible, hacked the firmware a bit - download below 🙂.

Had to investigate a bit for this one - per TK.'s design, ALT is the button above the SHIFT button, when SHIFT is pressed - this “two finger combination” also works in MatriX, so pushing and holding SHIFT and then pushing and holding the button above it (“16” on the extra column) will enter ALT mode.

Within ALT mode, e.g. on pattern screen you can save patterns, this already worked before.

Interestingly, TK. had made a conditional code section for ALT (see code snipped above) that it needed to be pressed on the virtual BLM keyboard for the missing octave selection - i’ve just removed this conditional and it works now as expected - SEQ v4+ internal firmware test version SEQ v4+/503 available here:
https://www.midiphy.com/files/b49/seqv4p-503-project.hex.zip

After uploading this new firmware to your SEQ v4+ (no change on MatriX required), you can switch octaves by pressing ALT and any other key in the left extra column. To do that, push and hold SHIFT, push and hold ALT (#16, the key above it), and then push any of the extra column keys above - pushing key #15 will switch to the lowest octave 0, pushing #14 will switch to octave 1 and so on.

Regarding using sliders or the joystick for this, can’t really change the internals of TK’s sequencer and his original BLM protocol, but glad to see that octave switching now works within MatriX - cool, if you could confirm if this trick works for you.

Thanks and best regards,
Peter

Thanks for the cool update Peter! This one has been on the request list for a few years now 🙂.

Best,

Wow, that was a quick response. And yes, now I can shift octaves, mute and assign cc’s as I like. Well done, Peter.
