Manhattan Analog – MA35 [matttech]

Manhattan Analog MA35 Demo 1

 

INTRODUCTION

For the first five demos I wanted to quickly fire off a number of 1 minute variations on essentially the same patch, in order to demonstrate some of the mA35’s tonal characteristics. All demos were recorded using the Intellijel Rubicon as the sound source, and centred around rhythmic sequences provided by the Doepfer a155.

The final two demos are from a slightly different patch, and centre around the MA35’s self-oscillation and FM capabilities.


 

DEMO 01 – Mode CV

Patch Details

Sound source: Intellijel Rubicon

On this I used the MODE CV input to switch between LP and HP modes, which – when the cutoff is set very low – almost acts as a VCA, cutting the signal in and out.

Slight reverb added during mixdown. No EQ.


 

DEMO 02 – Mode CV & Envelopes

Patch Details

Sound source: Intellijel Rubicon

Similar patch to Demo 01, but this time, every time the filter switches to HP mode an envelope is also applied, which adds an upwards cutoff sweep over the top of this change.

Slight delay added during mixdown. No EQ.


 

DEMO 03 – Internal VCA

Patch Details

Sound source: Intellijel Rubicon

This recording features some OSC Sync action from the Rubicon, and also showcases the internal VCA in the MA35, with a very snappy z4000 ADSR controlling it.

Slight delay added during mixdown. No EQ.


 

DEMO 04 – Self-Osc & FM

Patch Details

Sound source: Self-oscillation / Intellijel Rubicon

This demo kicks off with no audio input to the filter, but instead we hear it self-oscillating. After a while some Rubicon waves are faded in, and some FM applied towards the end.

Slight chorus added during mixdown. No EQ.


 

DEMO 05 – Self-Osc & FM

Patch Details

Sound source: Self-oscillation / Intellijel RubiconThis demo shows off the MA35’s FM abilities – initially just acting on the self-oscillating filter itself (FM provided by Maths), and then Rubicon waves are gradually brought in. The frequency of the FM from Maths is tweaked during the recording.
Slight chorus added during mixdown. No EQ.

DEMO 06 – HP Self-Osc & FM

This demo shows off the ways in which the MA35 can be used to create interesting sounds, even with no signal input – and also focuses on the Highpass output. All signals were recorded direct, and the VCA used was the internal MA30 one.

Some wigglers on Muff WIggler had been discussing how the MA35 has a certain amount of noise in its circuit – well, it DOES…but so did the design that it is a clone of – and also you can put this noise to good use: If you FM the filter, with no signal present at the input, it will produce an output that sounds like a oscillator wave – even with the resonance turned down to zero. Presumably this is the small amount of noise in the circuit being FM’d. As you turn up the resonance, you will gradually morph the signal into something more recognizable as a self-oscillating (FM’d) filter.

Bringing in an actual oscillator wave underneath all of this alters the sound again. this filter has bags of character, and I’m liking more each time I play with it.

Patch Details

1. Intellijel Rubicon Sine and Pulse are fed into Input 1 of the MA35, via an attenuator whose level is gradually increased as the recording progresses.
2. The Rubicon’s pitch is controlled by the Turing Machine’s main output.
3. 00:00 – 00:40 – No audio input. This is merely the sound of the MA35 with zero resonance being FM’d by a Dixie Triangle wave, which is following the same sequence as the Rubicon.
4. 00:40 – 01:30 – Here the resonance of the MA35 is gradually increased, adding some “proper” self-oscillation into the mix
5. 01.30 – The waves from Rubicon are finally brought in underneath the FM/Self-oscillation sounds.
6. The MA35’s cutoff is also being modulated via its 1v/oct CV input – by an output from the Turing Machine’s Voltages expander, producing a different, although related, sequence from the main module. This goes through Maths, serving as a slew limiter.
7. The second channel of Maths provides the spiky envelopes that control the MA35’s VCA level.
8. During the recording various controls are manipulated: MA35 FM amount (CV2); Resonance; the level coming from the Rubicon into the MA35’s audio input; the shape of the Maths envelope (from Linear to Exponential); the Fall time of the Maths envelope


 

DEMO 07 – LP Self-Osc & FM

This demo continues in the vein of the previous recording, and shows off the ways in which the MA35 can be used to create interesting sounds, even with no signal input – this time using the Lowpass output.

Patch Details

1. The patch is identical to the previous one, except for the addition of some modulation into the MA35 VCA’s Gain CV input – coming in at audio rates from the Dixie. This is only introduced for the ending.
2. The cutoff of the MA35 is also manipulated this time round, with the combination of low Cutoff and low Resonance creating the growly effect heard from 02:30 onwards.
3. As with the previous recording, various other controls were manipulated – including the slewing of the Turing Machine pattern applied in Maths.
