  1. MPC-style drum pads

    in Testing/Troubleshooting

    Posted

    I just did the e-drum project. It's also cool. I made some drum pad's with cheap training pad's. Now i try to make some smaller pad's to record bongos etc. I got good results with a old small metal soap can. You just have to stick a piezo in it. That's all.

    I also made some small pad's 5x5cm. I used a piezo, a aluminium 2mm and a piece of neopren rubber on it. But the result was disapointing. I had to hit very hard to get a velocity more than 64.  :-[

    I send more info's as soon as i know what's the best to built. (And play)

    I made the tb-303 clone from Carlos Germany (LosDos).

    http://home.t-online.de/home/TB-303/tocd.htm

    The clone works and the sound is much the same as the original. It's the same schematic as the original. The pcb is not very professional. Broken pipes etc. You have a lot to do the get it to work. It's also a bit expensive. The midi-interface is using a 80C31 and in the part description a some expensive transistors. (You can use the much cheaper us versions)

    Next time i would use the one from oakley sound. Much better pcb and some extra features like cv/gate/accent/slide in etc. But i don't know if it sound exactly the same as the original. It's a slightly modifyed schematic.

    The TR-909 is from Trevor Page:

    http://www.resonance.fsnet.co.uk/

    It's an very professional PCB. But a lot of work! 2 PCB's to do and the part's will cost about 300 Euro.

    I have all the part's now and now it's time to start...  :D

    So, i really don't know how this thing sound's, but it should be the same as the original. The schematic looks the same.

    Ok, let's see and wait till Horsten is back from holiday. It would be very cool to use more than 8 channels. With 2 MF modules and some cores or with a extended MF module that support 16 or more channels.

    I have a 16 in and out interface for my pulsar/scope card and do the mixing on my scope but i need a mixer (controller) for my main parts of my scope mixing.

    But it's not urgent, first i have to finish my tb-303/midibox and my tr-909 clone.

    Regards,

    Ok, let's say i do it with 2 core modules and 2 mf modules. 1 connected to it's core module. Do i need an other core for the 64 potis and for the buttons or can i use one of the others?. Can i link the 2 core's so i need just one display and don't recognize that 2 or more core's are working in the back?

    Regards,

    My next project could be a 16 channel mixer with a mute, solo button a pan and 4 aux potis on each strip.

    How many channels can i control with the MF module?

    I need 80 potis, 17 motor. faders and aprox. 64 buttons. Is this possible?

    Yees, thank you. I tried i just in independent mode.   ::) But there is still a little problem. My tb plays a slide when i note is legato. The Slide Led is flashing on every note, it doesn't matter how short a note is. I tried this in combined mode. Is the MIDIbox playing every not legato? Is this possible?

    I made a TB-303 Clone and try to use my MIDIbox 64 as sequencer. My clone uses velocity to control the accent, so i have to control - note - velocity and note length with my MIDIbox. Is this possible?

    I could control the note and the gate but not the velocity.

    best regards,
