I want to implement a stand-alone variant of http://www.maxforlive.com/library/device.php?id=196 What I want to achieve: I want to select quantize grid, feed clock to the core and play live, but with getting quantised output. Has something like this been done? What's the best approach? I was thinking of using the NoteStack from MBSEQv4 and pushing/popping notes on the notestack based on midi clock.

I am trying to format the built-in SD-Card from my SeqV4 via MIOS Terminal (sdcard_format), but as soon as I type it in incl. the "Password", the Sequencer seems to crash (it doesn't react to keypresses anymore etc.)

I'd love to take care of it! Email sent!

@westlicht Thanks! Yes, it's true that handling more than 1 BLM could present a problem, but I imagine it would be possible to daisy-chain them and add some firmware mods to allow for that (or use STM32F4 core, which allows for USB Host, so the LP can be attached via USB).

I am looking for either completed Sequencer or only assembled CS for the MBSEQv4. The MBSEQ I've built 4 years ago has not survived my move. Price: Make me an offer. Thank you!

Here is an initial version including source code (still very messy, but works). Any extra contributions and comments greatly appreciated! Source Snapshot: https://files.no-route.org/LaunchPad-BLM-master-f7d75f24d74542e1ecec3eb0a66f2dbe1b7629e0.tar.gz SysEx Firmware Update: launchpad_blm.syx

Haha thanks ;) I will do some code cleanup and then I will release my stuff as open source. One of the reasons that I did it was actually because the out-of-the-box functionality of the launchpad was not so useful for me.

I have written a BLM-compatible firmware for the Launchpad Pro. No modifications on the Seq V4 side required :) This uses the "SDK" from the first post, which contains a proprietary library for the Hardware Abstraction Layer. I re-implemented most of the things from scratch. For the first prototype I borrowed the SysEx state machine from MIOS.

Video of the success: @Admin: Can someone move this maybe to the BLM category if its more appropriate?

Hello, Some time ago Novation has partially* open-sourced their LaunchPad Pro Source Code. The Device contains a STM32F103, has 8x8 Pads with Aftertouch and Velocity Sensitivity, DIN MIDI IN/OUT, USB-MIDI and 32 General Purpose Buttons. I always loved the MidiBox Sequencer V4 and built my first just after it got released. I never built a BLM, though, but played around with the Emulated version, which I liked! Now my Idea: Implementing the BLM Firmware on the LaunchPad Pro and connect it via DIN-MIDI/USB-Host to the SEQv4 as a Standalone device without the need for a PC as BLM-Launchpad-Proxy. My question is now, if I have to look into the source code of the PIC based BLM or if there is any protocol reference for the BLM protocol? I guess maybe looking at the Lemur BLM Code would make sense? * https://github.com/dvhdr/launchpad-pro - Contains proprietary HAL UPDATE: Success! BLM-compatible firmware based on the Launchpad Pro template working. Still has some weird bugs, which look to me a bit like memory corruption or maybe OOM. Anyone wants to help?

My Progress so far (and I'm stuck): declare -x MIOS32_BOARD="STM32F3DISCOVERY" declare -x MIOS32_FAMILY="STM32F30x" declare -x MIOS32_GCC_PREFIX="arm-none-eabi" declare -x MIOS32_LCD="universal" declare -x MIOS32_PATH="/home/wrk/src/mios32/trunk" declare -x MIOS32_PROCESSOR="STM32F303" and my patches: https://git.no-route.org/syso/mios32/tree/master @Tk: Maybe you could take a quick look? Initialization code, peripheral drivers etc. are included. Cheers

Hi there, What's the best procedure for porting MIOS32 from the STM32F4 to the STM32F3? CMSIS is available for the F3 and I think the initialization code could be adapter easily. Please point me in the right direction :smile: Thanks Syl

Ther interesting thing is now: Lemur connected finally, but still no packets visible. Pressing "Start" on the Virtual BLM also doesn't trigger anything.

I've checked the routing and networking is really not the problem in this case. ICMP packets (ping) does nicely, TCP/IP too. I tried using port 10001 as Local Port and 10000 as Remote Port, but this didn't fix the problem that there is no OSC incoming / outgoing from the LPC17 core.

Hello, I have been testing OSC on the LPC17 Core and even with udpmon set to 4, I cannot see any incoming or outgoing messages. What I tried so far: I set network to dhcp set osc_remote 3 192.168.64.252 set osc_local_port 3 8000 set osc_remote_port 3 8000 set osc_mode 3 1 set blm_port OSC3 and start BLM Emulator for OSX. No success. Also no success with Lemur. I can verify that there is no packet filtering in my local network - UDP should pass without any issues. Also what BLM Emulator does: it crashes after a delay of 5s after clicking on the connect button.

Hi All, I know this is a "historical" post, but well - Lemur has been released for Android and I would be interested in building a little setup!

Hi guys, After building my first MIDIbox sequencer V4 back in 2011 () , which is now unfortunately not longer functional, I decided to build a midibox sequencer V4 again. Is Wilba still offering his Front Panel and PCBs for the V4 (http://www.midibox.org/dokuwiki/doku.php?id=wilba_mb_seq)? I wanted to make my own front panel PCB with shift registers as SMD parts on the front panel, so it's saving a bit more space, but if the PCBs would be still available including the Panel, I'd probably go that way. Another question (without looking on the code now) is: Can there be more than 2 HD44780 LCDs added (or additionally a SSD1306 OLED)? I am planing to use the 2 x HD44780 40x2 Characters for the Standard Functions, but little additional OLED-Displays for some track info. Cheers sylwester

Hi there, I am currently building a hybrid synth (together with LemonHorse) and we are looking for a good (and reasonably priced) source for the SSM2044 VCF and the 2164 VCA. Any tips greatly appreciated!

Hello, I have built a ML-303 Clone which uses a MX20 ARM for sound generation etc. and the analog ENV, VCF of the original 303 for the rest of the audio path. For the rest, I use a small version of the MBSeq V4. I would like to sell my one and only piece, because I need to get money for my current analog synth project (which will be open sourced). This is how my synth sounds: https://soundcloud.com/seal-bergstr-m/diy-synth-digital-wavetable-oscilaltor-analog-tb-303-filter

I'm currently planing a little synthesizer experiment: a web controlled synthesizer + sequencer (with live audio streaming) which consists of the following parts: - JS/HTML5 Frontend (finished) - Server-side Gateway (to MIDI) (finished) - Audio Streaming (via Icecast2) (finshed) - Programmable Hardware Sequencer (to be done) In order to do this, I want to implement a MIDI-Controlled sequencer, where I can set the Track Length, Groove, Step Value, Gate, Velocity etc via MIDI CC Messages. What do you think is the best effort of building the Sequencer? I have a spare CORE_STM32 and CORE_LPC17. Cheers

Hey, I've started to build a very small prototype of my MIDIbox E-Drumkit. This started as I've been watching a documentary about Kraftwerk and I just remembered my old drafts for a velocity-sensitive drum tigger. Components needed: LPC17 core, voltage divider, current-limiting resistor, piezo buzzer This is it so far (yeah, the video is kind of boring, but it's intended for showing that everything works ok. What do you think? I'm planning to build a complete drumkit. But next time bigger pads, hats and also drum pedals.
