"This thing is great for dreamy evolving pads, drunk sounding horns, lofi surfing, and 80’s car chases.

The filter is modded to allow free playable control over cutoff and resonance, with a 2 pole/ 4 pole switch installed for more variety.
The chorus has been modded to allow adjustment of the rate, going into audio range for ringmod-like effects, adjustment of depth, and a true mix knob allowing for control between fully dry and fully wet.

There’s an external input, so you can run some audio signals in and override the noise (ext input level follows noise/filter envelope).

The internal battery has been replaced with a battery clip for no-solder battery swaps and a brand new battery has been installed.

All the tact switches have been replaced, so no annoying switch bounces while trying to program a sound.

The instrument is painted to match the green lettering in the programmer menu."

TINRS Fenix IV Update

An update via This Is Not Rocket Science:

"Fenix IV assembling parts
Six more weeks until Superbooth…

We are working hard on the first Fenix IV prototype and alternate between 'this is madness' and 'this is awesome'. Probably both are true.

All the parts has been tried and tested in Experiment Boards 1, 2 and 3. Everything works and we are happy with our sounds and effects. Now these parts have to make a mythical beast. The CPU plug-in boards and filter voice boards are in the mail. Chips are being ordered. Power, midi and plug board are in-house and partially assembled. The tiny headphone board is ready. Our interconnect board – connecting the modules to the jacks and replaces the wiring harness – will be ordered together with big board. Flying in from all over the world, all the pieces are coming together.
