Not sure for a 9090 but generally a drum sound has no sustain and triggers on NoteOn, Note duration does not matter, but NoteOff must be received between 5 and 10ms after, just to permit the same NoteOn to be received again.

Id pin(PA10) is floating externally but pulled up internally(cpu), connected to ground externally for host mode. Core must be restarted on each Dev/Host switching. There's no jumper or other option on PA10 it's directly connected to CPU pin. So check continuity between R3(Dev/Host switch) and the Core, this line should be broken you just have to find where... R3 is not really necessary and can be replaced by a piece of wire.

You can set your SQ80 in LOCAL OFF, Keyboard will act to MIDI OUT but not to SQ80 Sound engine. And use it as a Master Keyboard. Of course internal sounds can still be played from MIDI In and internal sequencer MASTER PAGE > Set KBD=MIDI(instead of BOTH). Best regards Bruno

@Phatline You're right, It's a toy! Cause I'm like a child when I play with it :) It's very instinctive to create grooving melodies and other bass lines with it. I will do a demo in video ASAP... -
Salut Thierry, I'm not the best to answer this question, I don't know NG, but after reading its concept page, it seems NG supports up to 2 velocity sensitive keyboards (like known from MIDIbox KB) So i will say NG ;) Best regards Bruno

Hi, Home-made desktop version finished. It's not perfect, but it's a good idea of the final version. Best regards Bruno -

If it's configured as OFF the signal just stays in idle state, it does not switch as a power rail, it stays a logic signal. I suppose this was made strong, depends on what is inside, logic buffer, transistor, cpu pin directly, depends on the current it can support; What I wanted to do here, is avoid any interface box and get IN and OUT, and it works fine with a Merris. With your solution you just recreate this interface box(regular optocoupled midi input) and power it with a logic line from the pedal and without Output. Here the original and well known diagram of a regular MIDI IN and Thru. Your diagram is just a part of it ;)

Hello, this diagram is a regular MIDI input stage, it's not a passive circuit and must be powered, if you connect the 5V to the ring you will get issue when the pedal send data. The ring is the TX point which has idle state at 5V but 0V on data transmit and use it as a power source is also not a good idea, it's a CMOS/TTL signal.

first timer builder looking for suggestions
Antichambre replied to synthmania's topic in MIDIbox SID
Yep, noise generator is right, the design for SID control is old but still very complete. If you follow the diagram and he "how to" you will quickly get some result, and get some good vibes from your SID, with CC etc... You can also find some clean board at Modular Addict. CORE8 + SID Module. Migrate the firmware to an ARM like arduino is an hard work, and you will not be able to use the MIOS Studio which is very usefull to program your patches etc... Best regards Bruno -
IIC output is using 2 buffers, the STM buffer set to 1024, the 16F84 buffer which sized to 96 bytes. I'm not sure but IIC is faster than MIDI then for a file size of 4104 bytes the STM will send 1024 bytes at a time and the PIC will overflow, not because of buffers sizes but just because it can't forward the data fast enough. To check but the buffer of the PIC can't be bigger... You can try to reduce the speed of the IIC but not too much cause it will delay all messages, just enough to avoid overflow. Or the best idea is to use a regular MIDI Out for your Yamaha FM ;)

Good song and beautiful pictures... Drones caused a lot of security issues some years ago. I can understand that rule too. Seven years ago here in my area a drone hindered rescue by helicopter from doing their job properly endangering the boat crew stranded on the coast. But some have authorisation, those ones are friend of mines, from school. They are lucky people cause it's now their job ;) https://www.pixnfly.com/en/

The HAARP Desktop case prototyping.
Antichambre commented on Antichambre's gallery image in Members Gallery
With a simple bender It's a very cheap one(not a press), not easy to use(not very precise) but enough for me. https://www.ebay.co.uk/p/2255535496 You can fix it on a strong table Or you need a very heavy vice ;) this one is a legacy of my grandfather, in fact the entire workbench is a heritage -

Hello... I hope everyone who is stranded at home has found a good occupation! Here some picture of the Desktop version enclosure. Shape of the side face, I found some ebony for the wood sides ;) Check of the assembly before paint. Some more pictures in the HAARP album. Best regards Bruno -
