Alesis DM5 - Pioneer Squid
The 1U module can be triggered with MIDI & analogue triggers.
How to recall Drumsets
The DM5 has 21 Drumsets available, each of which has 61 programmable drum sounds.
To recall a Drumset on the DM5:
1. Press DRUMSET
2. Turn the VALUE encoder to select a Drumset
Editing The Triggers
The DM5 has over 500 drum sounds arranged into 8 Families.
These consist of Kick, Snare, Toms, Hi-Hats, Cymbals, Percussion, Effects and Random Samples.
To assign a new Voice to a MIDI Note or External Trigger Pad:
1. Press VOICE, then press NOTE CHASE
2. Play a note on your MIDI controller or a Drum Pad
3. Press the CURSOR> button until you have selected the Voice Family parameter on the top left corner of the display. Choose one of the families listed above using the VALUE wheel
4. By pressing the CURSOR> button one more time you can then select one of the Voices in that Family using the VALUE wheel
Triggering with MIDI
Using the Pioneer Toraiz Squid
Looks like there are 12 triggers.
Set up midi channel (using channel 1 in this case)
To choose the Drumset, press group then voice on the Alesis drum.
You scroll through the sounds with the pitch /cc knob on the squid

My Son - Hindu Temples - Vietnam
This is a collection on Hindu temples in Vietnam.
It's really odd to see this kind of architecture outside India.
It's near the source of the Thu Bon river..... which flows to Hoi Ann.
The temples date between the 4th to 13th centuries.
Much was destroyed during the Vietnam war.

Moog Modular - 901 VCO
The Moog 901 came out in the late 1960's .. possibly 1965 to 68 ??
It's what is called a first generation VCO.
You can use this as a VCO & VCLFO (voltage controlled LFO)
It's a classic, and arguably this oscillator has influenced all VCO designs..... not just of Moog, but of synth manufacturers from around the world.
Below are VCOs from a ARP 2500, a Korg MS 20, and 3 Eurorack manufacturers.
The 901 is basically a 901a + a 901b in a single panel.
I understand it was the precursor to the 901a/b/c/d (please let me know if I'm mistaken).
There are 4 fixed outs .... sine , saw, triangle, pulse. ,.... all available simultaneously.
Level of these fixed outs is 0.5V RMS (-4 db).
600 Ohms impedance.
Sine:
Saw:
Triangle:
Pulse:
There are also 4 variable level outputs... which opens the window to mixing the different waves in varing amounts and sculpturing new waveforms.
Their range is 0 to 0.5V
There are 3 CV inputs.
There is a CV span of -4V to +6V according to the manual.
I like to keep it within the range or 0 to +5V
The frequency span of the VCO is 0.1 to 15Khz
There are 6 ranges: Lo, 32", 16", 8", 4", 2"
(Lo is good for LFOs)
The tuning of these oscillators definitely drift... but it's part of their charm :-)
I've read that Wendy Carlos had to tune them again and again while recording.
It might be the stability of the power supply ??
The manual states that keyboard tracking is a full 5 octaves... though I think maybe 2 octaves is more
reasonable. Still I love their sound.
Any temperature variations will cause large fluctuations.
Power supply requirements: -6V , +12V regulated.
-10V unregulated.
This is the view of the rear.
The PCB mates with a 22-pin connector.
(Tyco Duo-Tyne flag 22 pin edge connector)
The connections are
1. +12V
2. Ground
3. -6V
9. Sine out
11. Triangle out
12. Pulse out
14. -10V
16. Sawtooth out
Below is a pic of the 901a & a series of 901b modules
The VCOs were designed to work in banks, with a single 901A oscillator driver module.
In this pic, there are four 901b oscillators being driven by one 901a controller.
According to the manual, up to twelve 901b oscillators can be chained to one 901a controller.
The idea behind this was so just one set of CVs (from a keyboard for example) could drive a bank of 901B VCOs and they would track nicely together.
901A controller module
There are no output jacks. Only CV inputs.
There is a CV span of -4V to +6V according to the manual.
I like to keep it within the range or 0 to +5VPower supply requirements of the 901a : -6V and +12 V regulated. Max current is 25ma.

The connections are

Korg Volca Beats - midi mapping
Perfect for live performance. The sequencer is a bit limited. so midi mapping to an
external sequencer would be useful.
I'm using the Pioneer Toraz Squid as my midi sequencer.
So the volca doesn't start playing the moment you start the Squid
you need to enter the Global function setting.
1. Start the Volca while holding the func key, wait for it to start.
2. press step 6 (the light should go off), press Rec.
Now the sequencer will not start when you press play in your DAW or your Midi sequencer.
(It looks like the default midi receive channel is 10... the same as the Roland 707 & 909).
I'm leaving it as it is.
If you wish to change the midi receive channel:
1. While holding down the MEMORY button, turn on the volca beats.
2. Step buttons 1 to 16 correspond to the MIDI channels 1 to 16.
Press the button that corresponds to the desired channel, and the LED below the
step button will light up
3. When you have finished specifying the settings, press the (REC) button.
The settings will be saved, and the volca beats will be restarted.
If you decide to cancel the settings, press the (PLAY) button.
Also in the Global setting
1. Start the Volca while holding the func key, wait for it to start.
2. Press step 7. MIDI RX ShortMessage
Set to off (St.oF)
3. press Rec. to save
There are 10 voices to map
1. kick C2
2. Snare D2
3. Lo Tom G2
4. Hi Tom D3
5. CL Hat F#2
6. Open Hat A#2
7. Clap D#2
8. Claves D#5
9. Agogo G4
10. Crash C#3
Renaming projects in squid
* use the shift, main knob, Track Button & back button ..
Press shift + press main knob = space.
Shift + back = delete
arrow keys move forward & back
* shift + Track --- you can rename tracks, change their colour, etc
-------------------------------------
*** The Volca sample has a different midi implementation to the Volca Beats.
In the Sample, each voice has its own MIDI channel. ***

Korg MonoTribe - Midi triggering.
Synth & Drums
mY monotribe has been fitted with midi. I can't remember what kit I used. Sorry. Those were the days before I documented everything in a blog.
It's a very useful synth. So simple.... yet enough for the foundation of a track.
Just 3 drum voices & a mono synth.
Synth: Use midi channel 1
Drums: It’s using the standard General MIDI specification for drums,
which means the Drum section is triggered on MIDI channel 10 using the following notes .
Name Note number Note name GM drum name
BD 36 C1 Bass drum 1
SN 40 E1 Snare dum 2/Electric snare
HH 42 F#1 Closed hi-hat
This works for DAWs like Abelton
-------------------------------------------------------------
Note: your sequencer might be different.
I'm using a Pioneer Toraiz Squid. You'll need to shift the notes up an octave.
Name Note number Note name GM drum name
BD 36 C2 Bass drum 1
SN 40 E2 Snare drum 2/Electric snare
HH 42 F#2 Closed hi-hat
The Pioneer Squid its a revelation for me. Thanks Mitch for the advice. It's allowed me to re-use lots of my old synths & drums in unconventional ways.
----------
Turn off all active steps in the monotribe sequencer, otherwise this will play the moment you start
your external sequencer.
Turn down the noise.
