  1. Hi, I'm a blind software developer and accessibility consultant and I've wanted a truly accessible sequencer for a very long time. I'm wanting some advice as to the feasibility of modifying the Seq 4/MIDIFi Seq 4+ design to send the display text to a speech synthesizer like the Parallax Emic2. This is a serial device requiring data to be sent at 9600bps. The challenges would be how to tap the display data and provide the additional electronics to transmit it at the required data rate (would the extra alectronics and the speech board actually fit in the case?). Speification of the Emic 2 at: (https://uk.rs-online.com/web/p/signal-conversion-development-tools/7813055/). I don't have the electronics skills to determine if this could be done, but it would be elegant as only one additional hole in the casing would be required for the audio output. Another approach I could follow would be to take out a maxed out Seq 4 and dedicate one pair of MIDI input/output ports to transmitting display/LED data to an external PC/Mac application with the text encoded in system exclusive messages. The application would also send sysex request messages for things like: "screen contents", "current parameter name" and "current parameter value". I've written such applications before (my SurfaceReader application makes control surfaces like the Mackie Control Universal talk, see: http://www.raisedbar.co.uk/surfacereader/surfacereader.htm). This would require firmware modifications (as would the electronic-based mod), but I'm a c++ coder so this shouldn't be too much of a push for me. I suppose the downside of either approach would then be having to diff and modify my custom firmware to keep track of the official release unless I could bring my code up to the point where it could be incorporated into the official offering as an optional feature, which would be wonderful. I'd appreciate any thoughts, suggestions and advice as to how I could take this idea forward (or forget it completely). Many thanks in advance.

I'm wanting some advice as to the feasibility of modifying the Seq 4/4+ design to send the display text to a speech synthesizer like the Parallax Emic2, which is a serial device requring data to be sent at 9600bps using 2 pins of a 6-pin header. 2 more pins are used for gound and +5V and I believe the other 2 pins aren't used at all. I don't have the electronics skills to determine if this could be done.

  2. Hi, I'm a blind musician and A MIDIBox Lite looks like a good solution for me, but I'd like some advice on a couple of component choices: 1 - Can anybody recommend suitable buttons for the GP buttons that have good tactile feedback (i.e. a reliable "click", not a spongy rubber button)? 2 - I'd like to add the encoder option for setting BPM so, again, could anybody recommend a good quality one that clicks around rather than being a smooth action? Many thanks in advance. Tim
