Dual Voltage Controlled Low Frequency Oscillators.Who'd ever thought the humble LFO could be transformed into such a powerful multi-talented tool ?
ÆMIT has designed a dual voltage-controlled low frequency oscillator with unparalleled synchronization possibilities, and a slew of other clever features which will most certainly revive interest in this somewhat forgotten bastard child of the oscillator.
Both LFOs boast a very wide frequency range, easily going from 16 minutes per cycle to well into audio territory. Voltage-controlled rate, externally resettable waveforms (hard sync), and selectable unipolar or bipolar outputs are common to both as well.
LFO A features a variable waveform output - morphing from sine to square - which is, needless to say, under full voltage-control.
LFO B has selectable waveform outputs, and features an extra random output. While lacking the morphing ability, LFO B offers a built-in VCA instead, which makes the separate sum output (a+b) all the more powerful.
LFO A can be clocked externally, either by listening to any incoming signal, or by manually tapping a tempo. In either case, the LFO's rate can then be dialed into a musical division- or multiplication of the external clock. This unique ability makes this LFO sit comfortably within any rhythmic chain of a modular synth.
LFO B can be slaved - or synced, if you so wish - to LFO A's internal or external clock, and derive a division or multiplication of it. By doing so, LFO B can effectively follow any external signal too, and do that in a musically meaningful way.
Because LFO B's cv inputs - fm and am - are normalised to LFO A's output, it becomes easy to create more complex waveforms and rhythmic variations to simulate thrillers, arpeggios, accelerandos & decelerandos, note bursts and bouncing ball events.
We like to think of TWO LFOs as the first (and perhaps only) linear modulation source which truly deserves a well-earned place amongst the generally more accepted modules like VCOs and the like… It just blends in naturally, and makes itself quickly indispensable in any mature modular synth setup.
Pairs well with anything that can be modulated. :-)
LFO A :
- Continuous VC Morphing between Sine, Triangle, Saw and Square waveforms.
- Pulse output with variable pulse width.
- Internal mode : internal oscillator with exponential FM.
Listen mode : external listen input with threshold, sampled/held or tracked with multiply/divide.
Tap mode : tap tempo with multiply/divide.
- In Listen and Tap mode, FM works as phase shift.
- Selectable waveforms : Sine, Triangle, Saw, Ramp and Square, plus Stepped Random.
- Waveforms can be sequenced @ Rate/Ratio speed.
- A+B output : output A plus a voltage-controlled portion of output B
- Internal mode : internal oscillator with exponental FM.
Slave mode : follow LFO A with multiply/divide.
- In Slave mode, FM works as phase shift.
- AM and FM inputs normalled to output of LFO A.
- Output is selectable to be bipolar or unipolar.
- Lo range : 0,001 (16min) - 1Hz
Hi range : 0,1 (10 sec) - 100Hz (1600Hz with multiply * 16)
Lfo range : 0,2 (5 sec) - 20Hz; fine control thanks to the limited range of 100:1
- Multiply/divide uses 1/4 note as default, range is from 1/64 note to 4 whole notes with dotted notes and triplets.
- Reset input (hard sync).
- All settings are automatically saved when powered off, and restored when powered on again.
- Skiff friendly : 41mm deep behind front panel, including power header.
- Shrouded header on the power supply connector, no risk for reverse polarity.
- Includes printed manual and power cable.
- tba +12V, tba -12V, 0mA 5V
