Quick and Easy USB MIDI to CV Gate using Teensy 3.6

Quick and Easy USB MIDI to CV Gate using Teensy 3.6. Digital pins 29, 30, 31 and 32 provide gate outputs. A21 and A22 provide CV outputs.

MIDI channel 1 note ons and offs are mapped to A21 and A22 for pitch and velocity CV, as well as pin 29 for gate. MIDI channel 22, notes C, D and E are mapped respectively to pins 30, 31 and 32.

All pins are connected to 3.5mm outputs via a 1n4148 diode and a 1k resistor. No other hardware is required.

Sidechaining with the Optomix

I think my favourite use of the Optomix module is as a sidechaining tool. Very smooth!

Trail: Kangaroo Island Wilderness Trail - 4 Nights

I walked the Kangaroo Island Wilderness Trail last week. The five day / four night trail was fantastic. Lots of different environments to walk through, from bushland, forests, grasslands and stunning coasts.

The facilities provided for on the trail are first class, with clean, modern camp sites, plenty of rain water and a communal shelter / cooking area for walkers each night. The map and documentation provided for by Flinders Chase Visitor's Centre was excellent, and provided a detailed map, elevation and vegetation, and information regarding history, flora and fauna. Very well done.

The trail is well-marked, and can be completed without much training. I completed each day roughly within the time indicated, with a slow pace and plenty of breaks for photos. The opportunity to walk through such landscapes is amazing, and the KIWT is expertly organised / structured / maintained.

I had a magical time, and would highly recommend this trail.

Trail: Baroota Ruins - 1 Night

I spent the night at Baroota Ruins last Friday. The walk from Mambray Creek to the Baroota Campground is short, but very beautiful. There was plenty of rainwater at Baroota Campground. 

Doepfer A-143-1 Complex Envelope Generator as Simple Sequencer

The Doepfer A-143-1 seems to be a very versatile module. Due to the comparative, successive trigger the four envelope outputs can be used as a sequencer, where the decay and attack times of each envelope set the rhythmic length of that step.
