LPZW.modules TRAM8 MIDI Converter

Post by kay_k » Thu Nov 14, 2019 3:50 pm

Facts:
  • Intellijel 1RU format but alternative panels available (3U 5HP or 1U Tile)
    8 Gate outs
    8 corresponding Velocity outs
    3.5mm auto crossover TRS MIDI Input. (type A or type B outputs without adapter)
    Internal MIDI Thru for daisy chaining multiple TRAM8s
    12bit DAC up to 10V output on the CV outs (stock firmware sets 5V max for Velocity of 127)
    Backside switch for direct 5V bus or internal 5V regulator (from +12V rail) power supply.
    Alternative firmware to be loaded via MIDI SySex available soon (8 different Clocks and 8 clocked random S&H outs)
On our website

Now available thru Schneiders Laden @ 119€vat/100€net

Not so interesting to make a video about a MIDI converter .. but well I did one anyway:
[video][/video]

I am working on another prototype in the moment but as soon as this is in a usable state I will hack some alternative firmwares for TRAM8. One thing I will make for sure (cos I need it) is:
MIDI to 8 different clock (& reset) on the Gate out and 8 different triggered Randoms on the CV outs
I am open for suggestions, maybe I'll make the whole thing open source. If someone is interested in writing his own functionalities he can definitely ask me.
Firmware upgrade is via SysEx - I have a Phyton script for the conversion of the firmware hex to SysEx

This is how a 3U version in 5HP could look like.

For the moment the 3U version will be a special order thru me, I can't promise a delivery date. For now I can only deliver the panel for the user to swap them themselves.

Sweeeeeet! I like the 1U <> 3U conversion.

Does this work well with the BSP for a one-cable connection into the rack?

Exactly what I made it for. ;)
If you daisy chain 2 you have all drum gates and all their velocities by connecting just one cheap TRS cable. Combine this with the USB outlet from intellijel for maximum comfort

Sorry to kind of go off-topic - I love all the LPZW stuff!! I understand such a thing would be fairly straightforward to DIY, but have you guys ever thought about offering a 1U replacement panel for a WK1/WK2 combo? That would be a killer utility in 1U/20ish hp

Thanks!

Yeah def. thought about it. I even had a name. I just haven’t dug deeper yet cos with the WK2 you’d end up having the pots weirdly sideways.
If you want something like that anyway send me a PM or a mail thru the contact form of our website.

3U prototype panel.
They are going into production now but it will take until next year.
You can buy the 3U version directly from Schneiders when they will be available.

I've been working on one alternative Firmware today and I believe with nothing unexpected I'll release it next week.
Basically what I want to do is this:

Midi gets converted to different useful clocks on the Gate outs:

1: Run signal - goes high with start low with stop
2: clock 24ppqn (combined with gate 1 ist DIN SYNC, also works with Grids, Metropolis etc.)
3: clock 4ppqn aka 16th triggers.
4: 8th note trigger
5: clock 1ppqn aka quarter note triggers
6: half note shifted by a quarter (snare position in disco beats)
7: beginning of bar pulse
8: 16th divided by 3 clock

so since the CVs are free for whatever I planed for some triggered randoms
1: random triggered each 16th
2: random triggered each 16th
3: brownian random triggered each 16th (drunken walk)
4: random triggered each quarter
5: random triggered each quarter
6: brownian random triggered each quarter (drunken walk)
7: random triggered each bar
8: stepped ramp to go from 0-5V in a bar ??


so here is the place for some feedback on this before I pour the concrete!

FW update is via SysEx in case you wonder.

Another alternative firmware I am working on (release ??):

2x monophonic MIDI/CV for two channels
4xCC for a third channel (can be one of the above)
4x essential clocks


OUT---GATE----CV
---------------------------------------
1------GATE-----PITCH--------MIDI CHx
2------RETRIG--VELOCITY
3 ------GATE----PITCH--------MIDI CHy
4------RETRIG--VELOCITY
5------RUN------CC-----------MIDI CHz
6------24PPQN--CC
7------16th------CC
8------1BAR-----CC


any thoughts on this?

SO .. there we go:

here is the stepped random FW in BETA:
http://leipzigwest.org/LPZW/FW/Tram8_Ra ... rmware.syx

the original FW so you can go back:
http://leipzigwest.org/LPZW/FW/Tram8_v1_firmware.syx


I'd be super happy if someone would give it a try. Outputs like so:

1: Run signal - goes high with start low with stop
2: clock 24ppqn (combined with gate 1 is basically DIN SYNC, also works with Grids, Metropolis etc.)
3: clock 4ppqn aka 16th triggers.
4: 8th note trigger
5: clock 1ppqn aka quarter note triggers
6: half note shifted by a quarter (snare position in disco beats)
7: beginning of bar pulse
8: 16th divided by 3 clock

so since the CVs are free for whatever I planed for some triggered randoms
1: random triggered each 16th
2: random triggered each 16th
3: brownian random triggered each 16th (drunken walk)
4: random triggered each quarter
5: random triggered each quarter
6: brownian random triggered each quarter (drunken walk)
7: random triggered each bar
8: 16th stepped ramp to go from 0-5V in a bar

Since we do not need the learn button in this mode it becomes a manual freeze which holds the current CV outs until you release that button again.

I will make a video for this ASAP.

I just received the 3U panels.
A bit late for christmas but they will be available early 2020!

I really love this module. Still I have a feature/firmware request… Currently I'm using it with an Octatrack. Now, I can send up to four note gates per step per midi track from the Octatrack. But I can send only one single velocity value per step/track. So it would be really cool to have a firmware that outputs, say, ascending CC channels starting with 70 or so instead of the fixed velocity channel per gate.
gate 1gate 2gate 3
CC 70CC 71CC 72
That way I could send a CC value for up to eight parameters and trigger up to eight drum voices on just two Octatrack Midi tracks. Any chance this can be done?

By the way, that beta firmware looks really useful. I'm just afraid I'll need a second Tram8 to try it.

just got an Octatrack too (literally yesterday), so your request seems very likely to be applied. I need to do another thing first but yeah, very likely

This looks so immensely useful!

Is there a mode where each gate/cv pair can be a mono voice on a different midi channel?
Or four voices with velocity (and a gate for extra/random/whatever triggers)?

Is there (or will there be) a configurator to setup each output individually?

If the multivoicemode is possible I‘ll have to get two of these! One for voices from a midi sequencer and one for all the trigger/clock/random functions.

Wow!

Hi there,

weeeeellll I started out with a 2HP Midi converter that was never (or not yet) released. The plan for that thing was to be totally configurable but I failed creating the setup side of things. (webpage or little software)
So to rescue some of my work I created this module which is not that configurable but cheap. It was actually meant to be a straight forward converter just for drums. (I've been using the beatstep pro and a digitakt with it, it makes totally sense with them).

I started making alternative firmwares because .. well actually just for myself to get more use of the prototypes I have around :mrgreen:
The problem is that the CPU I am using is not the biggest one so code memory is actually a bit limited for a fully do it all MIDI interface.
Another problem would be to calibrate the outputs to an acceptable V/Oct precision. I am evaluating this in the moment.

This would be perfect for me an my octatrack if it could just put out 8 gates of the 8 octas midichannels + 8 CCs. Just like the default FW but on seperate Midi-channels with gate-on on any note. For the CV outs velocity would be more important than 1v/oct, so there is no need to calibrate it AFAIKS. Since I have a sequencer in my rack I use the OT as a 8CH gate sequencer and with the OTs complex but fast rhythmical settings per track and trig conditions that can get very powerful. Resetting LFOs, Use as Clock divider, "rare" gates to switch things....
