With the COVID lockdown currently putting a stop to any live music it looks like musicians are going to have to transition to live streaming for the foreseeable future. For musicians using DAWs this has always been a problem as the ASIO audio system cannot easily be routed into live broadcast software so I've spent some time hunting for a solution and settled on an open-source ASIO plugin for OBS studio. No setup needed in Cubase but I did have to use the loopback routing on my audio interface to route the DAW output to a spare input channel. So my live streaming ASIO setup will be as follows ...
- Cubase 10.5 running on two machines, synchronised by System Link over SPDIF
- Main computer runs OBS Studio with the ASIO Plugin by pkviet
- Maybe one or two phone cameras running IP cam software to provide individual feeds to OBS
For anyone interested in modular synthesis live streams I would strongly recommend the channel run by Robin Vincent at Molten Music Technology for providing friendly chat, gear news and much-needed humour in these dark days.
Well, we're all confined to our homes while the COVID menace stalks the streets so here's a goold old blast of insanely resonating modular synth with some 808 drums from Native Instruments Battery.
Just got this one completed and working. Uses the classic (reissued) CEM3340 chip as used in so many classic synths like the Sequential Prophet 5, Roland SH-101 and many others. The PCB wasn't quite right so I had to bodge wire a resistor and capacitor into the CV mixing section, not really worth fabricating a new PCB though as the finished module works very well.
What to do, what to do. I just can't decide.
I know. I'll make strage noises on the modular.
Made this today for a friend who's going to see Nile Rodgers in December, I thought it would be good to pre-empt the occasion by dusting off a few of my favourite guitars with one of my favourite riffs.
After several failed PCBs, we now have a working version that reads frequency from the modular! So far I've burned out four Arduino Nanos and a 20x4 LCD display module but we're getting closer to a working unit all the time. Next step is writing the rest of the firmware for the Nano to control the DAC and the 4066 switch.
Yes, it's another new (old) guitar. This one has been a "Holy Grail" guitar for me for a long time. I used one back in the 1990s in a studio in Newcastle and I always remembered it being a great guitar. Turns out they were built for Casio in the Japanese Fuji-gen Gakki plant that made the Japanese Fenders of the 1980s and the neck contour is exactly the same as my E-series MIJ Stratocaster.
Unfortunately, someone's done amateur repairs to this and soldered it up with jam and a hot spoon so the MIDI circuit is dead as a doornail and not coming back. No matter, I may even retrofit a Roland GK kit into this and have the world's coolest 90s tech guitar.
I stumbled across a video demo of a clone of the Buchla LPG on Youtube and was phenomenally impressed. So much so that I knew I had to build one. It's an ancient type of filter using Vactrols, a combination of an LED and a light-dependent resistor to effect a frequency response change. And it sounds wonderful.
The first PCBs aren't quite right, I managed to omit the two voltage tracks to the ICs so this first version is patched up with a couple of bodge wires to make it work. Only smoked one opamp making it, a new record.
Just arrived this week, an eBay special. The Novation Supernova has always been on my list of interesting virtual analogue synths so when I was looking for a Roland JP8080 and this popped up instead I didn't hesitate.
And it sounds bloody great. Absolutely pisses on the old MS2000, the filters sound really good (for digital filters that is) and it's got a really nasty clanky edge to it. Not figured out the arpeggiators yet but I've managed to get the LFO to sync to MIDI clock already. So that's good. And it would appear to be eight-part multitimbral. So I can can eight different programs playing in each performance patch. All with their own arpeggiator. No built-in sequencer but I never use those anyway. Brilliant piece of kit. genuinely dirty-sounding filter which reacts in a pleasantly surprising way as you crank the cutoff up.
To assist in my electronic endeavours I have treated myself to the very wonderful Rigol DS1054Z digital storage oscilloscope and BLIMEY, it is good. This machine does everything from FFT analysis to SPI bus decoding in realtime (almost). It's a four-channel scope, brilliant for watching the channels of something like an SPI or I2C bus.
So naturally the first thing I'd want to connect up was my modular synth. Here's the MakeNoise DPO oscillator outputs running in hard sync mode. FFT shows the harmonics and already I can see that I need to turn up the sweep extent trimpots for the pulse width modulation on two of my other oscillators.
The scope has LAN connectivity, PNG waveform saving to USB memory stick, hundreds of features you might normally expect to pay twice the asking price for.
And by illicitly googling "RIGLOL" you can find a page that lets you enable the paid performances for free.
Not that I condone such behaviour.
