Hey,
FYI: I found some interesting LED tactile buttons http://www.sparkfun.com/products/10440 which
should be pretty good suited for a BLM.

Okay, I'll find out where I can get the TLV5630IDW for the best price and then update this post.

Hi,
Is anybody organizing or would anybody be interested in a bulk order in germany
for AOUT_NG parts (including the TLV5630IDW)?
I'm thinking of managing such an bulk order if anyone is interested.

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.

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.

I'm also interested in 8 pieces if there are any left.

Hi,
In case any needs a C128 enclosure for his MIDIbox project for free send me a PM.
I'm living in Kiel, Northern Germany. But shipping might also be possible if anyone
want's to pay the shipping.

Hey nILS,
Heh, okay. Yeah, sure using MIDI for this purpose is quite low-bandwith and low-range, but
in some situations it's the only one way in order to control the gear.
Are you willing to share your source code, by the way?
Is this PIC or STM32 based?

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?
-
First, I'd check the traces connected to the shift registers (74HC165) and the solder points.
If you could make some close-up pictures I could check the it visually.
-
Are these soft-touch knobs with "D"-shaped axis? Do you have any vendor/part-number for them?

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:

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).

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.
[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.
