About unipolar and bipolar outputs

The bipolar output is not a mere scaled and offset

version of the unipolar output! It is made of two

bumps, a positive one occurring during the attack,

and a negative one occurring during the release.

PLL mode

Hold the frequency range (B) button for 1s. Tides

enters the PLL mode.

In PLL mode, a signal must be provided to the

CLOCK input. Tides will adjust its output frequen-

cy to match the frequency of this signal or a multi-

ple/division of it as set by the Frequency knob.

Hold the frequency range (B) button again to leave

the PLL mode.

Tips and tricks:

• Tides works wonders as a master modulator for

a classic analog VCO.

• When using Tides as an oscillator for bass

sounds, try both the unipolar and bipolar out-

puts; and the medium and high ranges - they all

sound different.

• Use the PLL mode to create just-intonation mel-

odies on top of a drone sent to the CLOCK input.

• A different fl avor of sync sounds can be ob-

tained by patching a PWM or square source into

the FREEZE input.

• Use the wavefolder on a low-frequency envelope

to create bumps and bounces.

• Use the PLL mode, and trigger the CLOCK input

from a rythmic sequencer.

• In typical Buchla fashion, the low/high tide out-

puts can be used to chain envelopes and create

complex shapes.

Calibration

1. Connect a patch cable to the FM input. Leave

the other end of the cable unplugged (this

prevents the normalling to +/-1 semitone to be

activated).

2. Connect a patch cable to the Level input. Leave

the other end of the cable unplugged (this

prevents the normalling to full amplitude to be

activated).

3. Connect a MIDI>CV interface or precision volt-

age source to the V/Oct input.

4. Hold the Mode switch (A) for one second. All

LEDs are lit in yellow.

5. Play a C2 note, or send a 1V voltage from your

CV source.

6. Press the mode switch (A). All LEDs are lit in

green.

7. Play a C4 note, or send a 3V voltage from your

CV source.

8. Press the mode switch (A).

The module is now calibrated for accurate V/Oct

operation!

About Tides

Tides is, depending on your point of view, a volt-

age-controlled looping AR/AD generator which

extends into the audio frequencies; or a dynami-

cally waveshaped synth voice with the ability to go

into subsonic territories.

Installation

Tides requires a -12V / +12V power supply (2x5

pins connector). The red stripe of the ribbon cable

(-12V side) must be oriented on the same side as

the “Red stripe” marking on the board.

The power consumption is as follows:

-12V: 5mA ; +12V: 55mA.

Controls

A. Mode selection. Goes back and forth between

one-shot AD (green LED), looping (LED off), and

one-shot AR (red LED) modes.

B. Range selection. Goes back and forth between

very low (green LED), low (LED off), and audio (red

LED) range.

C. Frequency/rate control.

D. Attenuverter for the FM input. When no sig-

nal is patched into the FM input, serves as a fi ne

tuning control.

E. Waveshape of the ascending and descending

segments.

F. Ratio between the duration of the ascending and

descending segments.

G. Curve transformation. From 12 o’clock to 7

o’clock (counter-clowise), applies a 2-pole low-

pass fi lter. From 12 o’clock to 5 o’clock (clockwise),

applies a wavefolder.

Inputs and Outputs

1. 2. 3. CV inputs for shape, slope, and smoothness

controls.

4. Trigger/Gate input. On a rising edge, resets the

waveform and starts the ascent. On a falling edge,

and in AR mode, starts the descent.

5. Freeze input. A gate signal applied on this input

can stop the envelope/oscillator and hold the

signal.

6. V/Oct input. 1V/Oct frequency/rate control.

7. FM input, controlled by the attenuverter (D).

8. Waveform amplitude CV - normalled to a con-

stant 8V source.

9. Clock input for PLL operation.

10. 11. End of attack (high tide) and end of decay/

release (low tide) outputs.

12. 13. Unipolar (0 to 8V) and bipolar (-5V to 5V)

outputs.
