Deluge Synthstrom - Single Cycle Waveforms
The Deluge synth can use SCWF (Single Cycle Waveforms) to create unusual oscillators.
Audio files less than 20ms are perfect.(but it can use waveforms that are longer)
The preferred format is:44.1kHz 16/24bit.WAV or AIFF up to 32bit 96kHz.
You can make these using Audacity.
Steps to load a SCWF into the Oscillator section
There are 2 ways I've found to load these:
Method 1 (short way)
1. Be in Clip/track view
2. Shift + Browse (this loads the first osc to the browser.
3. ‘bot-toP’ will scroll on the display to
indicate the bottom-to-top note range.
4. Press the select button
5. scroll to your SCWF folder
6. to change the SCWF , just press the Select knob again
7. use the audition pads to play.
Method 2 (long way)
1. Press the Clip/track button
2. Press the Synth button
3. Shift + Type (grid button) ...
4. Press select twice... you will see OSC 1 displayed
5. press select again ...you will see type displayed
6 Press select
7. Turn select to find "SAMP". (Sample)
6. Select a sample. Navigate to ‘FiLE’
7. Press select.
8. ‘bot-toP’ will scroll on the display to
indicate the bottom-to-top note range.
9. press select. navigate to your SCWF folder
To enter the Waveform view
1. Shift + Start
You should see the waveform with start and end points.
2. You can play it by pressing the Audition Keys.
3. Start = Green
END = Red
4. Pressing each will cause it to start flashing. You can move the start and end points.
5. You can zoom in using the left/right knob (hold down & turn) to increase the resolution.
Setting the start and end loop points.
1. Hold the start line with one finger and touch the new loop point with another finger
2. Do the same for the end point
3. Start = blue
end = purple
4. You can zoom in using the left/right knob (hold down & turn) to increase the resolution.

Power Supply - NLC - Build notes
Building a Nonlinearcircuits PSU.
This just supplies +/- 12V for Eurorack modulars.
Andrew's build notes are here:
http://www.sdiy.org/pinky/data/WAMOD3%20%20psu.pdf
The virgin PCBs
Ok, lets twerk
Keeping Miley happy.
In the NLC build notes, Andrew stresses the importance of isolating the regulators from the heat sinks.
The smaller heatsinks came with grommets and mica insulators, so I think I'll use those.
He also recommended using heatsink paste.
Andrew F recommended I use these - http://www.taydaelectronics.com/capacitors/electrolytic-capacitors/4700uf-50v-105c-radial-electrolytic-capacitor-19x40mm.html
25V caps are okay but better to get 35V or 50V rating. just to keep the action well clear of the edge.
Always bigger is better with heatsinks, smaller ones cant soak off so much heat so will limit the current output of the regs. With a small one you will only get 3-400mA, a big one will get you double that (roughly...very)
The other thing to watch is the proximity of the heatsinks to the caps.
They do appear to be pretty close in the pics.
My sinks don't appear to get hot but they could cause problems if the temp exceeds the cap ratings.
These caps have a rating of 105 degrees celsius.
------------------
This PSU also has space for a 78L05 regulator.
Most of these are rated at 100mA
However, a standard LM7805 can be as high as 1A
A LM7805 might be a good substitution
If you are substituting remember:
1. the pinout is different so the 7805 goes in backwards
2. the 7805 can suck a lot more current than the 78L05 (10x more) and can take as much as the 7812, so keep it in mind and dont try to overwork it.
No need to change caps.
I'm using 1K resistors for the LEDs
This just supplies +/- 12V for Eurorack modulars.
Andrew's build notes are here:

The virgin PCBs
Ok, lets twerk
Keeping Miley happy.
The PCB receives 12VAC from a plugpack/ wallwart
. The 1N4004 diodes split this into positive and negative waveforms.
The 4700uF capacitors then smooth out these waves
. The 7812 and 7912 regulators then convert the rectified & smoothed
signals to +12V DC and -12V DC and these are fed to the connectors to be distributed to your lovely modules.
I'm using 250v TDK film caps for the four small 100nf caps
Probably a bit overkill, but it's what i had in stock at the time.
Some pics of the 7812 & L7912 voltage regulators attached to various heatsinks.
The smaller heatsinks came with grommets and mica insulators, so I think I'll use those.

Double Knot - Synth
Thanks Cobramatic for showing me your new synth.
The Double Knot
...
It's very west coast. Uses Bananas for the internal patching.
http://lorre-mill.com/doubleknot/
Lots of great percussion.

Golden Rock - Burma
Golden Rock Buddhist pilgrimage site in Mon State, Burma.
This precariously balanced granite boulder was according to tradition lifted by the Lord Buddah
and placed in this spot over 2000 years ago. It has remained in this position balanced by some strands of Buddah's hair.
New Years Eve.
So many people but very few foreigners.
The Rock is covered with 24K gold leaf.
The faithful
A new day
............... and a New Year.
Happy 2017
Our transport back down the mountain.

Endorphin.es - Shuttle Control - choosing a USB controller
Some of the midi controllers that work with the Shuttle Control
The old Korg Nano Control
The OP-z is particularly interesting as it has 16 midi tracks.
The online editor was a bit tricky at first to decipher, but these settings seem to
work OK with the OP-Z
I decided to use jacks 5,6,7,8, & 13,14,15,16.
These correspond to midi channels 5, 6, 7, 8 which the OP-Z uses
for its Bass, Lead, ARP & Chords tracks.
I'm still experimenting with the rest of the jacks.
They could be sources of random voltages, LFOs, envelopes, Sync clocks, etc
-----------------------------------
To add a "analog clock" set one of the channels to
Omni syncronization PPQN+ 24 (1/4)
This is great for driving a sequencer
To divide the clock in half just use a PPQN +48 setting
----------------

Fairlight IIx - The 8 Inch Floppy Drives
Some pics of the 1980's 8 inch floppy drive.
A computer tech friend of mine said he remembered buying these for around $800 AUD back then.
This was a time when the average price of a new car was $9,000.
Taken from the rear of the computer. Ribbon & power cables removed.
The top of the drive
The underside of the drive.
In excellent condition considering its age.
That rubber belt looks good for another 30 years.
The DS settings select the drive number.
Things really haven't changed much in this time
This was the secondary fairlight drive - used for holding the Sound Disk.
It's setting was DS2
The primary drive for holding the OS was set as DS1
