Roland Phrase Lab - MC-09

The Roland MC-09 "PhraseLab" was first manufactured in 2002.
Roland describes it as a TB-303 emulator featuring an effects processor, a step sequencer and a 4 part phrase sampler.

It's basically a single DSP monosynth. .... ie, it's a digital synthesizer that uses digital signal processing (DSP) techniques to make musical sounds.There are bass (TB-303 emulator), lead and drums parts. There are six control knobs for tweaking the sounds.
They control tuning, Env Mod, Accent,cutoff, reso & decay for the lead & bass.
The rhythm section is the drum. The bottom 3 knobs set the volume for the bass drum, snare & high hats

There are 4 DSP effects : filter, Isolator, Phaser, Slicer.
You can apply these effects to any of the four audio loops (or to live inputs).in real time by tweaking the knobs C1,C2 & C3.

The audio looper is a bit limited in length (6 seconds) but it makes for excellent sounding one-measure techno.

You can either capture audio internally (from the bass, lead & rhythm sections) or externally via the RCA jacks. Once in the looper, the sounds can be layered and effects applied, live.

 Pattern sequencer for up to two measures with 16 beat per measure resolution

Midi in & out. (not thru).  Smartmedia storage. 

If you purchase a SM card make sure it meets these requirements:
Power Supply Voltage : 3.3V
Capacity: 2MB - 128 MB

RCA connections - a bit low quality.

Seven Minutes - Buchla, Euro & a CR-8000

This track heavily features the Roland CR-8000 with some glitch.
Also very present is the Buchla 208r and Eurorack Braids. 
It's a mostly live performance which has then been tweaked and enhanced in Ableton.

Also used is the Abelton formant filter on some random recorded TV conversation.
---- it is almost unrecognisable as human voices.

The majority of the drums is the modded CR8000 with some extra Ableton glitch added here
and there for good measure. Individual outs have Boss Echo
and Reverb pedals applied. The CR-8000 is manipulated in real time.

 Extra percussion is  provided by the Tiptop 808 modules processed through the Buchla 267e band pass filter utilising random voltages - they no longer sound like an 808!.

Trigger Riot is slaved to the CR8000 (on 16 pulse out mode) and controls the 808 modules and timing of the 208, 262v and also pulse's Braids.

The main Sequencer is the 208r on 5 step mode but tapped separately on the 208 and the 262v harmonic Oscillator, which is processed by the 288v Time Domain processor - that is that deep echoing sound.

The choices joystick is modulating the 208 and Braids.
Braids itself is used in a number of modes which are switched live on the fly.
Including the pulsing 'chord' sound and the Vowel setting.

Roland MC 505 - Groove box

The Roland MC 505 came out in 1998.
This is much larger & heavier that the MC-303 which kicked off the
GrooveBox family for Roland in 1996. It's starting to become collectable.
I picked up this on Ebay for $300.
There is a long list of notable users such as Beck, Radiohead & New Order.

The 505 has 64 voices (the MC 303 had 28) and the sequencer has 714 preset pattern,
200 user patterns, 50 user songs.

There are also 256 user sounds & 26 rhythm sets which include some picked from  Roland classics such as the CR-78, TR-808, TR-606, TR-909, TR-707 and R-8.

I use mine mainly for its 8-track MIDI sequencer. You can record up to 32 bars per pattern.
As a midi controller it's quite flexible. The sequencer is easy to program and can be recorded in real time or step time.
You can input notes three ways : from the MC505's own black/white keyboard, the D-Beam controller or from an external MIDI keyboard.  All knob & fader movements can be recorded just like in today's Elektron synths. --- all this knob & fader tweaking can be "exported" via midi to external gear, making this a very powerful midi controller.  Ie, the 505 transmits MIDI Controller & System Exclusive data. WOW !!!!
(The MC-303 didn't have this function).

The heart of this synth is a 64 voice polyphonic digital subtractive synthesis engine that is based on the Roland JV-2080. It's all based on samples & is actually a compact version of the Roland JX-305 Groovesynth without the full set of 61 keys. There are 251 different oscillator, acoustic and drum sample waveforms.

There is built in Reverb, Delay and 24 different EFXs - they are not too bad.
 The verb & delay are pretty standard. The Verb has the usual settings of Room, Stage and Hall. An interesting delay effect occurs when you sync your delays to the patterns.
The EFX includes a 4-band EQ,  compressor, overdrive, phaser,  chorus, flanger, etc etc.
I quite like the phono setting which adds pops & crackles - like on a vinyl record. There are 33, 45 and 78rpm settings.

The nfrared D-Beam controller for hands-free sound modulation is very cool. You can tweak you sounds in real time by passing your hand over the beam. You can control one parameter (eg filter cutoff, pan resonance) at a time. The movement can be recorded into a Pattern - its a bit like the parameter locks you will find in most Elektron gear.

The mixer section is very useful. The faders let you control the volume of the 8 sequences.There are 7 synth sequences & one drum sequence
R = rhythm / drum part. 
The faders also control panning, keyshift and effects. At the bottom of each fader channel is a select/mute button

There is a a headphone socket and six outputs.
You can use these as three stereo pairs or as six individual outs.

RAM card slot at the rear (2Mb or 4Mb SmartMedia cards).

Nazcar Peru - Chauchilla Cemetery

Nazcar is famous for two things:
The Nazcar lines (more about this later) and the Chauchilla Cemetery.
The Chauchilla Cemetery contains mummies - some dating to 200AD.
The bodies are well preserved due mainly to the dry climate 

Much was plundered over the centuries. It's protected by Peruvia law.

The bodies were clothed in  cotton and then painted with a resin. it's thought that the resin slowed decomposition.

The tombs are made from mud bricks.

2000 year old corn.

Fresh Corn. And it's white - we don't see this variety in Australia.

Ace Tone / Roland - Rhythm Ace FR-2L

This beautiful drum machine was produced in 1967. It was the second drum to be manufactured by Ace Tone, which was destined to become Roland (1972). The Rhythm Ace was developed by Ikutaro Kakehashi, the founder of Ace Tone.

In 1967 the Hammond Organ Company also distributed Rhythm Ace products under the Hammond brand. The Ace Tone FR-2L was also sold as the Hammond Auto (1972).

The Cymbal, Claves & Snare buttons are very useful on the FR-2. In comparision the FR-1 had voice cancelling buttons for Cymbal, Clave, Cowbell and Bass Drum.

The sound of this machine is wonderful. It's very closein tone to my FR-1. It's warm analogue tones are as beautiful as any of my drum machines ... even the CR 78 and TR-808. The circuit boards are all discrete components.

The controls are as simple as they come. Just 2 knobs for volume & tempo.
The rhythms are all preset. You can push two buttons in at the same time to create more complex patterns.

Looks like this was meant to sit on top of an organ. It's lovely to behold.
As far as I can tell, the FR-2 came in 2 models The FR-2L which you can see above &
the Hammond Auto Rhythm FR-2D which came out in 1972. The FR-2D is almost identical to the 2L apart from having a solid wood book stand & a black face plate.

Super Sloth & Chaos - NonLinearCircuits - Build notes

A nice and easy build today.
The NLC Sloth/Chaos is a really cool module to have.
I have one in Serge format but it's equally useful for my Eurorack gear.
I can best describe this as a very slow LFO. Cycles can last between 15 secs
& 15 minutes. Andrew has two versions.: Slow or Super Slow. I'll probably
build both, but this page will be for the Super Slow Version.

Three-toed-sloth (Bradypus variegatus), Lake Gatun, Republic of Panama

Here is a link to Andrew's NLC website where you can purchase these Sloth PCBs.
His main website is here.
And his blog.
Muffs Thread.
The Build notes & BOM for the Sloth are here.
2nd muffs thread.

First some pics of the virgin panel & PCB:

.IC and Power headers first:

Resistors & Caps next.

The components for the Sloth & Super Sloth are different. 
For the Super-Sloth version, C3, C4 & C5 must be bipolar/non-polarized 10uF capacitors. 
For the standard Sloth these can be regular 1uF(not-electrolytic)(4.5mm spacing) caps.

The LED is also not your standard one. It's a 2 pin bipolar to show positive & negative voltages.

The two huge caps used are C1 & C2 - 1000uF electrolytic (polarized) / 35V
The 3 smaller caps are for C3,C4 & C5. They are 10uF/50V - NonPolarized.

LED next
The LED must be a two pin bipolar type to show positive and negative going voltage.
It's one colour when the voltage is +ve & another when in the -ve zone.

The final piece is to pick the LED resistor. It's marked RL on the PCB. Andrew suggests values in the range 330R to 10K

The 330R seemed too bright for my LED and 10k too dim.
Experimenting with a few different values of the LED resistor.
I finally went with a 1K resistor.

The LED is a 2 pin bipolar. It will change colour to show positive & negative voltages.

I was really amazed how the sloth does go to sleep.
At times it is inactive or an hour and you can be forgiven for thinking its not working.
Then suddenly things happen.

So decided to build a standard Sloth today.
This uses 100uf caps for c1 & c2
 The LED resistor is 560 ohms.
 C3,C4 & C5 are  regular1uf non electrolytic.(You can prob try using surface mount here).
 C6 & C7 are surface mount.10uF (16V)

Works a treat :-)
