  1. 279d01bba613b352646d73f8da05ea66487b1cf5.thumb.jpg.5e5b7af33624898bb4ff3cbc3eba6337.jpgHi all,

    I am trying to midify my Crumar DS2. It does not appear to have a traditional keyboard matrix. It has 44 keys, each one send 5v when pressed to an 8 bit encoder circuit. I would like to wire in a Midibox that adds midi in. I imagine I would have 44 connections sending 5V via a couple of DOUT boards. Which project would be best for this application, the Midibox 128 or the Midibox KB?

    Thanks!

  2. My controller doesn't send a MIDI clock, just start and stop messages. I got it to work by going into MIDI config, Ext. Controls. There I could assign one button to start/stop it via CC messages. So that works for me. Thanks!

  3. Hi there,

    I was wondering if there is a way I can get my midi controller to control the transport on my Seq4? I read that there is no MMC control for the Seq4. Can I assign CC messages to start and stop my sequencer? 

    Thanks!

  4. Hi there,

    It is triggered with a combination of a trigger and an accent. Thorsten changed the firmware so it can provide individual accent levels for each instrument, like the 909. So the sequencer can handle velocity.

    As for pcbs I kind of lost my way with this project. I was going to make a few pcbs and make a project out of it but life and other similar looking projects kind of dimmed my motivation to do that. I have eagle files for the pcb if you want them. The firmware obviously here somewhere too.

    Best

  5. Here is a clip of the Midibox drum Sequencer driving a TR-9090. I have one issue. When in Live mode  most of the drums do not trigger manually. I have a feeling it is because velocity is not being sent as well. Any ideas what I am doing wrong? Thanks!

     

  6. Hi there,

    totally new to all this scripting stuff. I'm probably posting in the wrong area, but not sure if I'm dealing with C or what. I think it is DOS, but really not sure. So sorry for my naivety in this area.

    Anyway, I am trying to change the frequency of my MBFM to deal with 16M rather than 14.31M. There is a perl script in the UTILS folder of the MBFM firmware release. I have dabbled with the script to deal with a frequency factor of 5555.5 (which I think is correct for 16M) So now I am just trying to generate a frequency table that I can use to replace the table in the freq_table.inc file. Hope that makes sense. This is where I am stuck. I run the perl utility, it scrolls though the frequencies, but I can't figure out how to save the info that the script is creating.

    Thanks in advance

  7. Hi there,

    I'm building a MBFM using a sammichFM base board.

    Voltage tests passed and have discovered no shorts...as of yet!

    The firmware is running fine.

    However I'm getting no sound at all. I'm thinking the problem may be that the 14.31 crystal I am using is one pulled from an old Commodore 64. It has 2 legs with a 3rd ground leg. Looking at the board I'm seeing only 3 of the 4 possible pads are being used. However I think what I'm using is a crystal rather than an oscillator.

    Is this probably my mistake?

    Thanks in advance

  8. Thanks,

    for I've labelled it sync, I think that is the one your talking about, so I suppose I will have gto get it to sync something...haven't really thought about it yet. What are you thinking of doin with it?

    Cheers

  9. Hello all,

    I am testing an MB-6582 with a home brew control surface.

    The problem I have is with the mod matrix. When selecting a source and target the leds work correctly as does the actual routing. The problem is that the target is not updated in the LCD. It stays with ---. The source is updated though as is the actual routing and led behaviour. So I'm confused.

    Any ideas?

    Cheers
