Lyra VR – pre-alpha of a sequencer for virtual reality

I’ve been working non-stop on this for the last couple of months (at the expense of all else as some of you know), and can finally share the fruit of those labors. It’s currently entered in two competitions, so please help us continue work on the app by voting here: http://www.istuary.com/pitch-competition-2015/281

Update

Lyra won the first prize in the AR/VR Track of the Leap Motion 3DJAM!!!

Attack of the clones

I ran into an issue with the Arduino Due clone boards I’ve been offering with the TB2 kits. It seemed the boards wouldn’t start properly when installed in the TB2 shield. After offering refunds and vowing to stop selling the clones, a customer alerted me to the fact that you simply need to press the reset button (circled in red below) on the board after plugging in the power for the TB2 to start properly.

I have a number of the clone Dues left, so I’ve decided to sell on the remaining stock. Just take note of the work-around if you decide to go for a clone. If not, genuine boards are available from Mouser.

TB2 – Mono Mode & Portamento

Version 131 of the TB2 Quartet firmware adds a monophonic mode with 3 different input types (highest note, lowest note, and last note priority). There’s a new unison mode with adjustable spread and number of voices from 2 to 4. Portamento has also been implemented. The parameters for these features can be saved o a per patch basis.

Turkish TB2

A grad student in electronic engineering  from Istanbul, Turkey shared these shots of his graduation project – based on the TB2.

Here’s what he wrote:

Looking at the last product that I made, it really has similarities with yours upon hardware and software design. I also really can say that I appreciate your design. I used a 16×4 LCD and I put some additional buttons. I left a gap in the upper right corner for a future sd card module. My design became actually a little bigger because I only had a chance of one layer pcb design:)

Very cool! (Click the pictures to enlarge)
