A happy sight

Wednesday, March 6th, 2013

This makes for a happy sight for sore eyes, parts for the next 20 Zira’s packed and ready to go to the assembly place (plus one assembled one so they have a reference should they need it).

A new Zira

Friday, February 22nd, 2013

I’ve finished building a couple of Ziras using the a new PCB. The new PCB fixes the mod made on the original. It also adds an extra trimmer which make setting them up a lot quicker. I’m hoping to have some of these ready for sale in the next couple of months. You can read […]

Zira available

Sunday, June 10th, 2012

Zira is now available to buy, it comes fully assembled and in a perspex case, you just need to supply MIDI, power (9V-12V DC @300mA) and plug it into your mixer. Think of Zira as a pocket sized monowave. Zira has the following features (full Spec can be found here); Two oscillators, each with 48 […]

Zira Update

Wednesday, August 10th, 2011

It’s been an interesting couple of weeks. I built a second Zira to test the remainder of the chips I have and start sending units to beta testers. But the one I built wouldn’t work, it lit up, you could edit values, save patches, load patches but would not respond to MIDI! I checked the […]

GorF Build guide

Thursday, July 21st, 2011

A few people have asked about some elements of how to build their GorF kits, so I’ve revamped the tron build guide to make a little more generic and updated the links. The new build guide can be found here and whilst it’s still about how to build a Tron the important parts (order to […]

Zira Update

Monday, March 14th, 2011

Well, I’ve got the LFO routing in now, just the LFO delay to sort and some debugging. I’ve also managed to get the two missing tracks into the Zira Demo, so it’s now complete. The missing tracks were the “ppg vocal” and the “wobbly bell”, I hope you enjoy this as much as I did […]

Zira demo

Saturday, February 12th, 2011

I’ve started recording a demo of Zira whilst I work on it. There’s still a couple of things left to add to Zira (LFO, Patch storage and MIDI CC’s) but it’s coming together. As a bit of a tease I’ve extracted two tracks from the demo, one is an analogue arpeggio and the other is […]

Zira Update

Friday, December 3rd, 2010

Well, the new board is here, and I’ve assembled it and you can see it above. I’ve already started coding and it’s a LOT quieter than the previous one, there’s no horrible buzzing on the audio from the display! In addition, we have sockets for all the connections, as shown below. From Left to Right, […]

Zira (PicoWave) Update

Sunday, October 24th, 2010

Well, I’ve had a few problems with this one. A few timing issues which I can fix in software, the biggest problem has been the display. The DLR1414 is incredibly noisy. So noisy you can here a high pitched whine over the sound you’re playing and also it puts so much noise on the ADC […]

It’s been a while, II

Wednesday, June 30th, 2010

Well, work has me busy, but I’ve not been completely idol in the little spare time I have. I’ve been tinkering with the code on Zira (TSKAPW – The Synth Formally Known As PicoWave), I just have the boot loader/MIDI Sysex update code to modify and test before Synth DIY. I’ll try and get around […]
