  1. [Instructions] How to build MIOS Studio for Linux

    in MIDIbox Tools & MIOS Studio

    Posted · Edited by sylwester

    Building MIOS Studio for Linux

    Here are my instructions for a successful build of MIOS Studio for Linux.

    I've tested it under Ubuntu 10.04 and it works without any problems.

    Please note: This requires a little bit of linux knowledge, as the JUCE v1.51 contains a bug in the

    MIDI port enumeration, which needs to be patched beforehand in order to use MIDI.

    Prerequisites

    - GCC Toolchain and GNU essential utilities (Package "build-essential" for Debian / Ubuntu)

    - Subversion (svn)

    - Copy of the trunk of the MIOS32 repository (svn://svnmios.midibox.org/mios32/trunk)

    - Copy of JUCE v1.51 (http://www.rawmaterialsoftware.com/juce.php)

    (Placeholder - Work in Progress. Please stay tuned.)

    For now, I'm able to provide a binary x86-64 release of the 2.2.2 version (see attachment).

    The MD5 Checksum of this file is is: d43ad373bb8b5c4ca856a4e4e5c0561a

    SHA1 Checksum: 11b4481193196ea675ded51f678c1e2740586e28

    Update: Official Binaries for Linux are provided by TK on ucapps.de in the MIOS Studio section! Thanks TK.

  5. [Idea] MIDI Envelope + LFO box

    in Design Concepts

    Posted · Edited by sylwester

    Do you think it might be more appropriate to start with the MB-SID app, which already has 6 simultaneous LFOs and 2 ADSRs? It's already equipped to send via AOUT, so perhaps the app could be modified to send the mod values from each source to MIDI OUT, at specific intervals.

    Well, as nILS already said MIDI is quite slow and you will be probably experiencing some bandwidth problems really soon.

    The source code I've got from nILS looks quite promising and could be modified in a quite short time in order use it with MIDI.

    I'll be doing that at the week-end and if nILS would agree, I'd share the source then.

  6. [Giveaway] MOS6581 with broken filter

    in Fleamarket

    Posted · Edited by sylwester

    Hi,

    I have a MOS6581 with a broken filter but the rest is functional

    (but for some reason, there a minimal amount of solder on one pin).

    It could be used with an external filter like SSM2044 etc.

    PM if you want it ;)

    PS: No, I won't put it on eB*y as others do.. I think I'm too

    faitful for doing that.

  10. [Idea] MIDI Envelope + LFO box

    in Design Concepts

    Posted · Edited by sylwester

    Hi,

    I'd like to write something about an idea I had recently.

    I've been thinking of building a stand-alone programmable MIDI Envelope Generator + LFO based on the MIDIbox core

    which almost has the LFO settings as used in the MIDIbox sequencer v4, but with more (and programmable) waveforms/

    wavetables and an envelope generator (ADSR/ADHSR) that might be internally routed by a routing matrix.

    From the technical point of view, I've been thinking about a box according to the KISS-principle.

    A 2x40 character LCD, a few buttons and one menu encoder, 4 x MIDI-Out, 4 x MIDI-In..

    What do you think about such an idea? Anyone interested?

  13. [SOLVED] SEQ v4 DIN problems / overall progress

    in Testing/Troubleshooting

    Posted · Edited by sylwester

    Hello,

    I'm just building my own MIDIBox SEQ v4 and have some trouble with the DIN (Digital Input) modules from SmashTV's Shop.

    The first two modules are working without any trouble, but a 3rd module doesn't work and all other DIN modules also

    stop working. I've checked for short-circuits, but I couldn't find any. I've also tried terminating the last DIN

    module + DOUT module with the resistor + capacitor terminator without any success.

    My wiring looks as following:

    - Core32 -> DIN(1) J1 outer pins

    - DIN(2) J2 inner pins -> DIN(3) J1 outer pins

    - DIN(3) J2 inner pins -> RC-Terminator

    The two first DIN modules work perfectly - every button press / logical state change is recognized properly.

    I'm powering the board via a 7.5V adjustable stabilized transformator power supply.

    This problem was caused by a wrong resistor network in R31. I had a 10K resistor network

    instead of 5 x 220 Ohm. Now everything is perfect.

    Thanks,

    Sylwester

    This is how the actual "test" looks like:

  14. Idea: Ethernet + SD-Card PCB

    in Design Concepts

    Posted · Edited by sylwester

    Thanks for your answers.

    Seppoman, I agree with you that OSC/Ethernet is rather a "Playground" feature than some feature

    that is going to be used "in production" by practical users. I really like the modularity of

    the project. I rather had this in mind for my rear-panel layout and was thinking that there might

    be somebody sharing my idea ;)

    PS:

    Today I've soldered the STM32-based core and 3 x DIN4X modules. As soon as I'm not ill any more

    I'll start working on the DOUT module and the front panel wiring.

    Any suggestions where I can get a 2x40 LCD with backlight for cheap? Got about 20-30pcs of 2x40 LCDs

    w/o backlight in case somebody needs one for experimenting (HD44780).

  15. Idea: Ethernet + SD-Card PCB

    in Design Concepts

    Posted

    Hey,

    I've been thinking about making some PCB which contains both the ENC28J60-based Ethernet Interface

    and a SD-Card adaptor (think of putting this on the rear side of a MidiBox Seq v4 etc.).

    What do you personally think about such an idea? I've seen the existing solutions (e.g. using an

    old floppy adaptor cable as a socket for prototyping, using a "break out board") but I'm looking

    for some kind of "solid-state" solution.

    Best regards,

    Sylwester

    PS:

    Right now I'm building my first MIDIBox device -- the STM32-based MIDIBox Seq v4. Today I've ordered

    the front panel from Schaeffer (which probably is the most expensive part of the sequencer. I've

    ordered PCB kits from SmashTV, due to lack of time. It seems like the german customs have stopped

    them from arriving here. But hopefully I can show you some results soon.
