Rakit Metal Synth***** Difficulty rating: MODERATE TO HARD
The Rakit Metal Synth has a Polivok’s inspired filter at its core. It uses this, along with a punchy AD envelope to produce a variety of percussive sounds from shaped noise.
It was designed to be a companion to the Rakit Drum Synth and as such creates a range of mad/interesting sounds and some very useful metallic sounds.Available as a kit or fully assembled.To find out more please read the full description below…Kit Assembly
Only two basic soldering tools are required to complete this kit: a soldering iron and a pair of flush cutters. You can check out the detailed assembly guide on the Rakit websiteThe kit is made entirely of interlocking PCBs and unlike most kits the only wires that have to be soldered are the ones going to the piezo disc.How It Works
The synth is triggered by a piezo disc which is sensitive to how hard you tap the top panel giving subtle differences in the two stage envelope.The noise is generated digitally by a pre-programmed microcontroller. The filter at the heart of the unit can be controlled and modified by the Sweep, lowpass/bandpass, Resonance, Cutoff and Cutoff CV.Powering The Unit
The Metal Synth comes with a 9V pp3 battery to barrel jack connector as standard. We recommend using an alkaline battery, this is not included.Should you wish to use your own power supply, please ensure it meets the following specifications:+8V to +12V, Centre positive 2.1mm (centre) x 5.5mm (outside)
Buy It Made
Don’t want to make the kit? No problem! The Metal Synth is also available to buy completely assembled and ready to go.
2x Trigger Options
Trigger by activating the piezo under the touchpad (Metal Logo) or by plugging in an external trigger.
So What Do These Twiddly Knobs Do?SENS: Sets the sensitivity of the trigger/touchpad.
DECAY1: Sets the decay time of the louder initial hit (body).
DECAY2: Sets the lasting decay
time (tail).
CUTOFF: Sets the filter’s cutoff frequency and the bias for control voltages to be summed with.
SWEEP: Controls the amount of sweep applied to the cutoff frequency.RES: Sets the filter’s resonance. The filter will oscillate at max!
AUX IN: A mono input of your choosing.TRIGGER, CUTOFF CV, AUX IN and OUTPUT connectors are all 3.5mm mono.
SOUND OUTPUT: The Metal Synth is capable of generating a wide range of frequencies and as such will work best with a wide range speaker/amplifier rather than a typical guitar/bass amp.But What Does It Sound Like???Mmm Flow Diagram goodness…What's Included In The Kit?3x 3.5mm Mono Socket & Screws

Rakit Drum Synth
DIFFICULTYRATING Hard*****
By: RAKIT
Price: £45-£65
Availableas a kit or a fully made unit, theRakit Drum Synth is based on the (now rare) Boss PC-2/AMDEK PCK-100percussion synthesizer. Not only does this Drum Synth do sonic justiceto the original but we have also put our own spin on it with extramodifications including: * Attack on/off
* VCO & LFO wave shape selection
* Pitch CV input
Thesounds are generated (using an external trigger such as the Rakit Baby8 Sequencer or by tapping a finger on the large touch pad) by a VCO (Voltage Controlled Oscillator)optionally modulated by a frequency sweep, LFO (Low FrequencyOscillator), Pitch CV (Control Voltage) or all three. There is a simpleenvelope generator with a fixed fast attack for punchy percussiveenvelopes and variable decay for super short to really long decays (5seconds+). The sounds produced by the synth are perhaps not what youwould normally expect to associate with drum sounds and can vary frombig bass drums to tapping on glass to UFO space drum-wobblythings!
The Rakit Drum Synth is madeentirely of interlocking PCBs and includes silkscreened artwork on allsides. Additionally unlike a lot of kits the only wires that have to besoldered are the ones going to the piezo disc.
Specialcare has been taken to make a kit that can be constructed with only2 basic soldering tools: a soldering iron and a pair of flush cutters. The skill level required to build the kit isintermediate (Some prior experience is recommended.) More information on the Drum Synth's functions plus clear instructionsare available at rakits which include large step-by-step photosand tips, and a page of example settings to get you started. Werecommend that this kit should take an evening (3-4 hours) to complete.
TOOLS REQUIRED
Soldering Iron & Solder
Flush Cutters
Pliers (optional but you might need them in a pinch [Ha!])
A battery snap to barrel jack cable is included as standard. We recommend using a good alkaline batttery (not included.)
OPTIONAL EXTRAS* 500mm leaded solder
* 9V PP3 Alkaline BatteryThis kit is compatible with the Rakit Baby8 Sequencer kit which you can see here in action on youtube.
