Notes: Dual xFade is a compact voltage controlled crossfader suitable for both audio and CVs. Smaller knobs set manual crossfade between A<>B, and bigger knobs are CV attenuverters. LEDs show the adjusted positive and negative CV sides for easy monitoring.

Upper inputs (section 1) are normalled to lower inputs (section 2). Thus the same signal pair A&B can be differently crossfaded in both sections.

The switch clones section's 1 controls to the section 2, which is useful to make stereo Dry/Wet adjustment or stereo VCA.

This module can be used as:

two independent crossfades

two independent VCAs

stereo crossfade or Dry/Wet control

stereo VCA

panner

Four jumpers on the back can give optional 5x amplification for each A or B input. Sot it is easy to crossfade modular level with linear level from pedals. Installed jumpers give 1x amplification, removing jumpers gives 5x amplification.

Output 1 is mixed with output 2 if left unconnected.

Notes: Clever FM module that does digital-style through-zero FM using analogue circuits. Use any signals from other modules as your carrier and modulator, then phase modulate or wavefold in the FM Aid.

Supplier's Notes:
FM AID is a module designed to perform through-zero linear Frequency Modulation (FM) in the analog modular world. Any arbitrary signals can be used as a Carrier and Modulator. The module copies FM in how it is done in digital implementation, but in a completely analog circuit free of digital aliasing artifacts. Digital or software FM oscillators are mainly based on a ramp waveform which is then shaped to other waveforms. This is also represented in the FM AID module: sawtooth signal is expected on the Carrier input to give the indicated sine, triangle, sawtooth and square waveforms on the respective outputs. However the user is not limited to only use sawtooth for the Carrier and any other signal can be plugged giving many complex waveforms at the outputs.

All known FM tricks from digital implementation are also applied - you can endlessly experiment with the Carrier/Modulator frequency ratios, Modulation index (FM knob), Modulator's amplitude shaping (CV knob), feedback FM (output is fed back to the Modulator's input) and many other.
Carrier input has normalled connection to the Modulator's input. This internal routing is disconnected each time a plug is inserted in the Modulator's input. That is a handy option which allows the module to be used with only one signal source - this single signal will act as Carrier and Modulator at the same time. There won't be any frequency differences between Carrier and Modulator in this case, but many interesting wave folding sounds will be available anyway.

Technically speaking FM AID uses Phase Modulation, not Frequency Modulation. The sonic difference is that the produces sound is brighter.

Notes: 32 unique audio effects arranged in 4 banks of 8 effects. Three effect controls plus analog Dry/Wet control with dedicated CV input. High quality stereo signal pass. Assignable CV input to effect controls or to Sample Rate reducer (changes internal clock). Four user storable presets - stores selected program and all three controls. Spin FV-1 based.

The last used effect, assigns and presets are always remembered.

32 effects are simultaneously available, but FX AID can be reflashed with other effects in any order.

Reflashing procedure is quite easy: playing 40 sec long "wav" file of line level amplitude to CV input.

Reflashing mode: hold both buttons for 10 sec.

Please note the reverse CV operation of the Dry/Wet control: positive CV crossfades from Wet to Dry, and negative CV crossfades from Dry to Wet.

By default it runs on 32.77 kHz and, if sample rate reduction assign is used, this sample rate can be decreased down to 150 Hz or brought up to 48 kHz.

Notes: 6xMIX is a six channel audio (AC coupled ) mixer, channels arranged in three groups with separate outputs having led indicators. Each group can be switched to mix with the subsequent group, allowing for 2-2-2, 4-2, 6 mix configurations. The module can also be used to mix two stereo channels plus separate group of two mono channels. Perfect audio performance with the lowest noise and distortion amounts.

The inner knobs control the A inputs, while the outer knobs control the B inputs.

Notes: 2xSAM is 4 HP Dual Stereo Attenuator-Mixer

Several 2xSAMs can be chained together or with other HN stereo modules via sockets on the back side.

2xSAM's total mix stereo output can be internally sent to the Isolator, PanMix Jr, 3xStereo Mixer, or can be received from OUT, PanMix, PanMix Jr, 3xStereo Mixer, or another 2xSAM.

If jumpers are not installed (placed on one pin only by default) the max gain is 1x. When the jumper is properly placed on both pins - the gain is 5x. There are four inputs thus four jumpers. Each jumper is relevant to its channel.

Notes: 3xVCA offers three high class amplifier circuits with linear characteristic. Thanks to AC / DC compatibility, a very low noise floor and basically no distortion, the module is not only a great partner for control voltages, but audio material as well. Besides a signal input and output, each VCA has its own CV input. The dual potentiometers regulate levels and bipolar CV attenuation values of all amplifiers. Using these rather unusual, yet very practical components, it was possible to equip the 3x VCA with a front panel that is only 6 HP wide. Switches allow the user to feed the results of one amplifier to the output of the next amplifier, so we can get 1+2, 2+3, and 1+2+3 outputs mix. Two-colored LEDs visualize CV and output signals.

Notes: LED Meter is a handy utility module designed to show audio levels. Three color versions are available:

- green colour with yellow-red peak segments.
- all blue colour
- all yellow colour

There are total 30 led segments, each one roughly corresponds to 1 dB of level, so it is 30 dB of measurement level available with this module.
The module has an input for the signal to be displayed, and its buffered copy is sent to the output for further processing, so no external splitter is needed.
Two trimmers are accessible via holes on the front panel: left trimmer adjusts brightness and right trimmer is used for the level adjustment. So the module can represent full scale signals ranging from 1 V to 12 V.
There is operation mode jumper on the back side. When the jumper is installed - bipolar operation is active, and when the jumper is removed - ordinary audio meter is active.

Notes: PanMix Jr is a high quality 3 channel mixer with manual panning and volume controls with dual concentric knobs. Each channel's output is separately available. Also channels 1 and 2 can be switched to be mixed with the subsequent channel, allowing for 1-1-1, 1-2, 3 mix configurations. Equal power pan law (3dB) is provided. Left and Right led indicators available for all three channels.

Several modules can be chained together via connections on the back side. This connection is possible with other Happy Nerding stereo modules too. At the moment PanMix Jr stereo output can be internally sent to another PanMix Jr, 3x Stereo Mixer and Isolator module. Or stereo signal can be received from another PanMix Jr, OUT, 3x Stereo Mixer, latest revision of PanMix.

Notes: HN VCF is a state variable filter having 12 db Low Pass, 12 dB High Pass, 6 dB Band Pass plus 18 db Low Pass marked as "LP!", because it has extra drive. All three parameters: "Freq", "Resonance" and "Drive" have dual knobs with outer knobs controlling bipolar CV amount. These affected CVs are then shown by the relative green/blue LEDs.

The possibility to have CV over "Resonance" and "Drives" makes it a very capable 6 HP filter.

"LP!" output has 6 dB steeper slope (18 dB) compared to ordinary 12 dB "LP" output. Plus it has much more drive.

Notes: 3xMIA is a 6-channel attenuverting mixer/offset/scale/polarizer

3 blocks of 2-channel attenuverting mixers, using dual concentric pots. Each channel can be switched to mix with the subsequent channel, allowing for 2-2-2, 4-2, 6 mix configurations.

With nothing plugged into an input, an offset is normalled to that channel. The inner knobs control the A inputs, while the outer knobs control the B inputs.

DC coupled, so it can be used for audio, CV, or both at the same time.
