Re: Has anyone here used a 3D printing service to make enclosures for projects?
I'm sure Blender will also let you do the same, for free, I just have never successfully got to grips with it. The core message, Shapeways laser sintered nylon is a REALLY good option. These are for old 1st generation Pi, but the concept is clear - a simple base to lift all the electrical contacts o...

Re: Has anyone here used a 3D printing service to make enclosures for projects?
I've had a lot of success with Shapeways' SLS process making Pi cases / bases, modelled in Cheetah 3D on the Mac.

Re: Raspberry PIpe Organ
A rather belated update to this discussion - this codebase runs flawlessly on a Pi 3, with 2 keyboards and a Swell pedal connected over USB.

Re: Raspberry PIpe Organ
... I should say, this response is equally applicable to physical pipe organs as it is to virtual ones, even though it’s phrased in terms of virtual. The ‘synthesis engine’ on a real pipe organ just being the embedded computer that manages the big bitmap of what pipes are speaking or not at any give...

Re: Raspberry PIpe Organ
It’s pretty brainless to get this right to be honest, and is actually way harder to get wrong than to get right. Since the synthesis engine has to maintain the current set of depressed notes in order to synthesise at all, doing the right thing - in terms of the engine internally commanding ‘pipes’ t...

Re: Raspberry PIpe Organ
MIDI is good for most instruments, but can struggle with 'real' organs. The problem is that it does not send 'keyboard note down', 'keyboard note up' messages, but sends 'note on', 'note off'. Since having multiple stops out means that each press of a keyboard note generates multiple sounds, the MI...

Just saw this thread, after I posted one of my own a couple of days back.

Re: Screen recording on Pi
It's not the most straightforward programming exercise, effectively boiling down to the work I did to support Minecraft over RealVNC last year - you need to collapse / composite the frame buffers into a single buffer then pass that into an encoder. For RealVNC that was a frame by frame JPG encoder b...

Re: Tracktion - professional DAW and interface hardware
TBH anything over USB - it's all dependent on how the Linux filesystem is implemented deep down in its bones, and I know nowt about that. The critical thing is, if the number of active pages/sectors/whatever that need to be kept open in RAM exceeds an internal implementation-defined limit you'll see...

Re: Tracktion - professional DAW and interface hardware
Re. USB drive - not so sure about that as an improvement. The nastiness with a DAW is you have a very large number of widely-scattered read points and write points to the filing system, in my current case 8 or 16 write points and up to 96 read points (tracks), so depending on how the file system is ...

Re: Tracktion - professional DAW and interface hardware
I have a DAW engine Ive written that can sustain well over 72 tracks of playback. RAM isn't the limit here, SD read/write speed is. So their quoted 32 is a bit lower than expected but still enough for somebody to make the equivalent of Sgt Pepper, Who's Next or Led Zep IV!! Very excited about this. ...

Pi Display - can I completely display the HDMI?
When I run using the Pi display (the official 7" thing) I see significantly worse performance than when using just HDMI. The only conclusion I can draw is that the HDMI subsystem is still burning memory cycles fetching and compositing the framebuffer - can anyone confirm or deny this, and indic...

Re: Disable video refresh for HDMI / composite?
Working, and happy to connect the additional cables between Model B+ and display board - I don't like micro USB for power so am more than happy to remove one of them. The biggest problem was PSU - I had an Apple 10W charger which seems to only be 5.0v unloaded, using a newer 12W 5.2v plus fat wires ...

Re: Disable video refresh for HDMI / composite?
Thanks for this. At least I now know this isn't the problem - I just read on another forum post that undervolt warnings cause the Pi to drop out of turbo mode, which is what's killing me. I need to improve my power supply situation and get 5v into the Pi over all those GPIO pins rather than the micr...

Disable video refresh for HDMI / composite?
Hi all I am seeing a dramatic performance hit when using the Pi display. Same SD card, plug into a Pi Zero at HDMI 1080p, runs fine. Plug into a B+ with a Pi display, big slug. I am assuming is due to the HDMI continuing to read framebuffers - any idea how I can turn this off to be sure? cheers Phil

Re: Raspberry Pi based Synthesizer
It's neither open-sourced nor ready to release. I'd love to take a look at what you've done but I fear I won't ever have the time!! But if you are getting 20+ notes of polyphony out of a Pi 1 you are getting something right, it is challenging to squeeze that level of performance out of these things....

Re: Raspberry Pi based Synthesizer
Rolling your own is absolutely the only way. The last time I measured I got some 50 notes of polyphony, 2 layers per note (e.g piano plus strings) on a Pi model A with my sample replay engine.
