maths is an analog computer designed for musical purposes. amongst other things, it will allow you to:
generate a variety of linear, logarithmic, or exponential triggered or continuous functions
integrate an incoming signal
with no signal applied, generate a variety of linear, logarithmic, or exponential functions
add, subtract and or up to 4 signals
generate analog signals from digital information (gate / clock)
generate digital information (gate / clock) from analog signals
delay digital (gate / clock) information
if the above list reads like science rather than music, here is the translation:
voltage controlled envelope or lfo as slow as 25 minutes and as fast as 1khz
apply lag, slew or portamento to control voltages
change the depth of modulation and modulate backwards!
combine up to 4 control signals to create more complex modulations
musical events such as ramping up or down in tempo, on command
initiating musical events upon sensing motion in the system
musical note division and / or flam
perfect for modulating the dpo and just about anything else
max depth: 24mm
power: 60ma@ +12v, 50ma @ -12v
maths revision 2013 is a direct descendent of the original maths, sharing the same core circuit and generating all the fantastic control signals that the original was capable of generating, but with some
upgrades, additions and evolutions:
1. the layout of the controls has been changed to be more intuitive and to work more fluidly with the forthcoming cv bus and existing modules in our system such as the dpo, mmg and echophon.
2. the led indication for signals has been upgraded to show both positive and negative voltages as well as to increase the display resolution. even small voltages will be readable on these leds.
3. as make noise now offers a multiple the signal out multiple (from the original maths) has been changed to a unity signal output. useful as it allows for creating two varitions of output, one at unity and the
other as processed through the attenuvertor. also allows for ease in patching function responses not possible with the vari-response control alone.
4. an inverted sum output has been added for greater modulation possibilities.
5. led indication for the sum bus has been added for increased signal awareness.
6. led indication added to show the state of the end of rise and end of cycle.
7. end of cycle output is now buffered for improved circuit stability.
8. added reverse power protection (to be compliant with the rest of our system)
9. added ±10v offset range. user has choice of ±10v offset at ch. 2 or ±5v offset at ch. 3.
10. added greater logarithmic range in vari-response control allowing for east coast style portamento.
11. the evolution in the circuit is the cycle input which allows for voltage control of the cycle state in channels 1 and 4. on gate high, the maths will cycle. on gate low maths will not cycle (unless the
cycle button is engaged).
