the rs-310 is a complex bbd (bucket brigade device) analogue delay line with variable feedback. unlike the simpler bbds found in other delays and comb filters,
it incorporates six unrelated "taps" at quasi-random delay points and with differing output levels. this means that an impulse applied to the input will result in at least six discrete
outputs in addition to the "dry" signal. the module is in good shape and works perfectly. click here for more

doepfer a-106-5 sem
the a-106-5 is a 12db multimode filter that is based on the filter circuit of the oberheim sem module. the filter is equipped with a band pass output and a
combined low/notch/high pass output. for this output a control knob defines the relation between low and high pass signal. if both signals appear at the same level (i.e. middle position of the
mix knob) one obtains a notch filter. otherwise the low or high pass signal predominates. the module does not feature self oscillation in contrast to most of the other filters of the a-100
system. the module generates a distorted audio signal if the level control is set to about 50% (i.e. center position) or more with a-100 standard signals like vcos. the module is in good shape
and functions perfectly. click here for more info.

doepfer a-110 vco
the a-110 is a voltage-controlled oscillator. this vco's frequency range is about eight octaves. it can produce four waveforms simultaneously: square, sawtooth,
triangle, and sine wave. the frequency or pitch of the vco is determined by the position of the octave (range) switch and tuning (tune) knob, and by the voltage present at the cv inputs.
frequency modulation (fm) of the vco is therefore a possibility. footage (the octave of the fundamental) is set by the range control, and fine tuning controlled by the tune knob. click here for more info. the module is in good shape and works perfectly.

doepfer a-113
the a-113 is a new sound source that derives from an incoming pulse signal four so-called subharmonics. the term subharmonics was introduced by oskar sala in
connection with his so-called mixtur-trautonium. a subharmonic means in this context a sawtooth wave whose frequency is derived from a master frequency and the master frequency is an integer
multiple in the range of 1...24 of the subharmonic - in other words: the master frequency is divided by an integer 1...24 to obtain the subharmonic. note: the doepfer a-113 module requires +5v
power. when using it in a doepfer case, an a-100 ad5 +5v adaptor board is required. the module is in good shape and functions perfectly. click here for more

doepfer a-121 vcf2 multimode filter
the a-121 is a voltage-controlled multi-mode filter with a cut-off slope of -12 db/octave. four simultaneous outputs are available, each with different
characteristics: low-pass, band-pass, high-pass and notch (or band reject). the cut-off frequency determines the point at which the respective filter effects appear. the frequency can be
adjusted manually, or by voltage control (filter modulation, for instance by an lfo or adsr). two cv inputs are available, whose control voltages are summed. click here for more info. the module is in good shape and works perfectly.

doepfer a-128 fixed filter bank
the a-128 fixed filter bank is a filter bank made up of 15 parallel band pass filters, all with fixed middle frequencies and bandwidth (50 hz / 75hz / 110hz /
150hz / 220hz / 350hz / 500hz / 750hz / 1.1khz / 1.6khz / 2.2khz / 3.6khz / 5.2khz / 7.5khz / 11 khz). each band pass filter has its own amplitude control knob, with which that frequency band
can be attenuated. the bandwidth of each of the filters is approximately half an octave. the signal at the output of the a-128 contains a mix of all the filters, depending on the position of
each one's amplitude control knob. the filter bank's main job is to emphasize individual sections of the whole audio frequency range. the module is in good shape and functions perfectly. click

doepfer a-145 lfo
the a-145 is a low frequency oscillator, which produces cyclical control voltages in a very wide range of frequencies. five waveforms are available: sawtooth,
inverted sawtooth, triangle, sine and square wave. the lfo can be used as a modulation source for any number of modules- for instance modulating the pulse width or frequency of a vco,
modulation of the cutoff frequency of a vcf, or amplitude modulation with a vca. the module is in good shape and functions perfectly. click here for more

doepfer a-146 lfo2
the a-146 (lfo2) is a low frequency oscillator which produces periodic control voltages over a wide range of frequencies. the lfo can be used as a modulation
source for a series of modules (for instance pulse width and/or frequency modulation of a vco, modulation of a vcf cutoff frequency, amplitude modulation with a vca). three outputs are
available, with different waveforms: sawtooth / triangle; square wave, and positive-voltage square wave. the waveform is continuously adjustable from rising sawtooth, through triangle to
falling sawtooth. the same control affects the pulse width of the square wave. a three-way switch can select one of three frequency ranges, spanning from one cycle every few minutes at the
lowest and up to audio frequency at the highest. the module is in good shape and functions perfectly. click here for more info.

doepfer a-171
the a-171 vc slew limiter is a voltage-controlled slew limiter, otherwise known as a portamento controller or integrator. it is the voltage-controlled version
of the a-170. whenever there is an abrupt transition in the voltage present at the input, the slew limiter works as an integrator, slowing down the transitions in the output signal so that
abrupt transitions are sloped. the steepness of the slope is governed by the rate control. the module is in good shape and functions perfectly. click here for
more info.

doepfer a-190 midi-cv/sync interface
the a-190 is a midi-cv/sync interface, with which you can control any a-100 module which has cv and gate/trigger input sockets by midi. the a-190 has two
digital-to-analogue converters (dac for short), which put out control voltages from 0 v to +5 v, so that you can control not just the pitch, but also another voltage-controllable parameter on
the a-100. dac 1 is 'hard-wired' to receive midi note messages and convert them into control voltages available at cv output socket cv 1. the dac has 12-bit resolution, which gives excellent
tuning resolution (in steps of 1/4096th). as a rule, dac 1 will be used to control vco pitch. dac 2 can be assigned to your choice of midi controller. click here
for more info. the module is in good shape and works perfectly. note: the doepfer a-190 module requires +5v power. when using it in a doepfer case, an a-100 ad5 +5v adaptor board is required (not included).
the motm-320 is a full-featured voltage-controlled low-frequency oscillator (vc lfo). unlike the crude lfos found in most synths, the motm-320 has 4 individual
outputs plus a master shape control. this control voltage will shift the shapes of the pulse, sine, and saw outputs in unison. both 1 volt/octave (temperature compensated!) and variable fm
(through a reversing attenuator to go up or down) inputs are available. another unique feature is a sync input: a positive voltage will reset all 4 waveforms. you can sync to just about any
waveform: from another lfo to eg's. the motm-320 is not your standard cheap lfo: it has a full-blown vco core with discrete waveshaping based on the moog modular and the vcs3! the core has an
astounding frequency range of 1 cycle in 30 minutes to about 2800hz. a bi-color led flashes at the lfo rate, and can be set with a jumper to indicate 4 different ways! click here for more info. the module is in good shape and works perfectly.
the motm-800 provides the standard adsr (attack, decay, sustain, and release) envelope for controlling vcas, filters, and other cv inputs. both positive-going
(0v to +5v) and negative-going (0v to -5v) envelopes are simultaneously available. attack, decay and release times can be set from 1ms to over 14 seconds using the smooth feel,
conductive-plastic bourns log pots. the motm-800 actually can be operated in one of 3 modes. gate & trigger: a full adsr (attack-decay-sustain-release) cycle, with re-triggerable ad portion
with gate on and a new trigger. gate only: a-d-s-r using roland "drop gate" synths (sh-101, etc). motm-800s generate full adsr cycles with gate only. trigger only: a-d cycle, useful for
"stretching" drum pad envelopes. click here for more info. the module is in good shape and works perfectly.

the harvestman malgorithm
the malgorithm is a voltage-controlled bit depth and sample-rate reducer, colloquially known as a "bitcrusher". from the severely reduced dynamic range and
quantization noise of bitwise truncation, to the unique frequency foldover of a low sampling rate, the "undesirable" side effects of early digital audio systems may be used as rich creative
utilities. this module provides such a system with a rich voltage control interface. the malgorithm is in good shape and works perfectly. click here
