    An alternative to the matchbook trick for organ…

    Somehow it never registered to me that you can do this with *more than one* note. Holding the E minor triad down while he plays piano during Runnin' Down a Dream is SO crafty.

    I added a latch switch button to a simple sustain pedal and wired it in parallel to the original switch, so I can play a chord and leave is sustained without keeping the foot on the pedal. I placed the latch switch close to the pedal hinge,  so it can be used in either way.

    Some Open Source woes

    Could that be a timing issue? If you are running the sample player through the Jack audio server (most probably you already know this, but just in case) have you edited the 'audio group'? (actually it is the /etc/security/limits.conf file that requires some change of settings from the standard linux configuration).

    Sending MIDI messages to the MODX in linux

    For those interested, a brief update.

    I tried the drumstick program, which is somewhat similar to amidi and sadly it is a similar story. Both the drumstick-metronome and the drumstick-guiplayer work fine with the Nord, but they do not work with the MODX.

    drumstick-vpiano does not work either with the MODX. I noted that the port is handled by alsa, so it might be the same problem as before (not being able to deal with the MODX ports).

    However, dumping MIDI incoming messages: 

    drumstick-dumpmid -p MODX:0

    works fine.🤔

    Thank you @pjd, I was aware of the description of the different ports in the manual and I tried all three visible ports, just in case.

    The piece of code above is a simplified version of my script (which is a loop, kind of a sample robot, which sends notes On and Off sequentially over a range of notes). I did try many other higher note values and it is still the same problem.

    I am coming to the conclusion that either amidi might be failing to address the MODX port, or I am calling the port incorrectly.

    (I note that the manual says that via USB one can use up to 8 ports with 16 channels, but only 3 are visible to amidi).

     

    I might explore using a USB-to-5pin MIDI cable and see whether that works, although I ignore which of those cable/interfaces work in linux (I read that many cheap ones do not work properly).

    I would be grateful for any other suggestion.

    Thanks again.

    Hi,
    I wonder if anybody has been able to successfully send MIDI messages over USB using the amidi command in linux. I also asked this in the Yamahamusicians forum, but I am not sure there would be too many linux users there.
    I wrote a script that works perfectly fine on a Nord Stage 2, but I cannot make it work on the MODX (where the only difference should be the hardware port where the messages are sent to).
    The amidi -l command lists the MODX interface ports as expected: 

    Dir Device    Name
IO  hw:3,0,0  MODX MIDI 1
IO  hw:3,0,1  MODX MIDI 2
IO  hw:3,0,2  MODX MIDI 3

     

    I am assuming that the ports should be accessible to the amidi command, but sending a Note ON message on Channel 1 (or any other) does not seem to work... The relevant lines are: 

    #!/bin/bash
i=16
vel=127
note=$(printf "%x\n" "$i")
velo=$(printf "%x\n" "$vel")
midi="90 $note $velo"
amidi -p hw:3,0,0 --send-hex=$midi

     

    The MODX is set to USB MIDI, Single Mode, Channel 1.
    The only thing I can think of is that in the Nord, the only hw port detected as a single number while in the MODX there are three (I did try hw:3,0,1 and hw:3,0,2, same result).

    I appreciate that the MODX and Montage have an "unusual" MIDI implementation, and I wonder if anybody has any additional suggestions.

    Thank you.

     

    Nord Triple Pedal woes

    Posted

    @cphollis: you might be remembering some other pedal. The original Nord triple pedal (not the one recently released with the Stage 4!)  has the same contacts as the keys (silicone contacts with carbon surfaces):

    This  diagram from the Nord user forum should be useful to troubleshoot what is going on:

    While it might make not a big deal of difference (depending on the sample), it is not the same thing using the L+R than only one output.

    Think of an Auto-pan stereo effect (bouncing L and R) if added as mono, you hear no effect, if you use only one input you would hear a Tremolo effect. You might get different types of phase cancellation by adding the inputs.

    Stereo Volume Pedal Questions…

    Is there a noticeable difference between using a 30k and a 50k pedal in terms of a more linear volume change throughout the pedal travel? 

    If the pedal is just a passive pot (many volume pedals are just that), I doubt that one can hear a difference. The linearity (actually logarithmic) change through the pedal travel is defined by the pot type (linear, log, anti-log).

    Strictly speaking now there are none of the original members of Yes in that group. When should the band stop using the original name? Is that a moral or a legal issue? I might be wrong but wasn't there also time when there were two touring Yes-related bands (can't remember if they both used the name). Similar to Focus where only one original member remains. My point was that it is a bit relative, like the ship of Theseus problem. The  Stones example, sure without Jagger it would not be the same, but why this is not an issue for Genesis without PG?
