Do you have a question about any of your Ginko Synthese products that’s not listed on this page? Don’t hesitate to contact me.
For PCB V2 (and up) this are the mappings of the inputs:
// Map Analogue channels #define SYNC_CONTROL (3) #define SYNC_OFFSET (0) #define GRAIN_FREQ_CONTROL (1) #define GRAIN2_FREQ_CONTROL (2) CV in1 is routed via potentiometer 1 and safety diodes to Analog input 2, CV in2 is routed via potentiometer 2 and safety diodes to Analog input 1, CV in3 is routed directly to Analog input 3 via safety diodes, Potentiometer 3 is routed directly to Analog input 0 with 5V on one side of the potentiometer and ground on the other.
What does the Sampleslicer do?
The Sampleslicer is a real-time monophonic sampler, including a 16 step voltage-controlled sequencer.The incoming sound is chopped up automatically into 16 parts by the incoming clock signal and spread out over the16 steps in the internal sequencer.
How long can it sample?
The length of the recorded sample is set by a clock-divider, so the recording time is always linked to the incoming clock signal. You can choose between time divisions of 1, ½, ⅓, ¼ and ⅛.
If the divider is set to 1 the total sample time is equal to 16 incoming clock-pulses.
If set to ½ the sample length is equal to 8 incoming clock-pulses, spread over 16 slices (so half the time). It will produce even more glitchy fun when set to ⅓, as it will spread 6 steps over 16 slices. The maximum sample time is about 15 seconds and the minimum sample time is a fraction of a second for granular noises.
How does the sequencer work?
Inside the Sampleslicer there is a 16-step voltage controlled sequencer to play back the sound. Every step is dedicated to a 16th part of the recorded sound inside memory. When the 16 steps are full the sequencer starts playing from the chosen start point till the chosen amount of steps are played. This can be in one-shot mode or in loop mode for infinite looping.
The start point and play length is determined by potentiometers or CV input.
Last but not least the individual slices can be played back as notes via CV from a sequencer or keyboard, by setting the start point in V/oct mode and play length to 1.
How does the pitch work?
There is a control to pitch the slices up or down. The pitch control affects the overall pitch of the recorded material. It can be controlled via CV.
There are 4 pitch modes selectable by the "pitch mode" button on the frontpanel. Next to the 4 pitch modes there is a 5th mode to unable the pitch control.
Why only realtime sampling?
My vision on the modular world is that you get most fun out of realtime created sounds. Out of principle I chose to make this module without a memory card reader.
What about the soundquality?
The sample rate is 12bit, just like the good old sampling madness days. A lovely sound with a slightly raw character without being too gritty. For comparison: CD digital sound quality is 16bit, gameboys are 8bit, the E-mu Emulator is 8bit, E-mu Emax is 12bit, the MPC60 is 12bit, the AKAI S612 is 12bit, the AKAI S900 is 12bit, Oberheim DPX1 is 12bit and the EMU sp-1200 is 12bit too…
What is aliasing?
If you experience noise in combination with some audio sources (but not all), then most probably you use digital audio sources with a lot of sharp corners in the audio. This may causes aliasing, which might sound as a pitched noise. If this is the case with your setup, simply put a lowpass filter in front. If you send digitally created audio through a lowpass filter the corners will be rounded off, the highest frequencies will be filtered and the aliasing/noise will be gone.
Analog audio will sound clean unfiltered and will have nice smooth aliasing.
Read more about aliasing on Wikipedia.
So, no, it is not 24bit as we know in the mastering studio’s. Instead, it will remind you of the good old “hip hop” sounds from the 80’s :) and it’s lovely! In the end it’s an instrument by itself not a mastering tool.
Be creative and try the module in any way you can think of! Feel free to share your results. I am excited to see what you come up with!
What can I put in the CV input?
The module is protected for overload. So basicly you can put anything in the inputs.
The start point and end point only reacts on positive values between 0V and 5V.
If something is fed into the CV inputs of the start point and end point the knobs react as an attenuator. This means that the CV input does not do anything when the knobs are set fully counter clockwise.
The pitch will react on negative voltages too. The pitch CV input is mixed with the value from the pitch knob, so when the pitch knob is turned fully clockwise the pitch will only react on negative values from the CV input. When turned fully counter clockwise the pitch will only react on positive values.
The startpoint pot reacts weird!?
There are two "presets" for controlling the startpoint. If the "0-5V/V/oct switch" is set to V/oct the incoming cv is calculated for use with an external keyboard tuned to "C". All black keys are ignored and the potmeter will have a different curve than on 0-5V.
It does not sample!?
If you press "sample" it does not start recording and all LEDs light up. No panic! This means your clock is too slow to keep the recorded sample within the memory. To solve this simply speed up the clock a little.
I hear a lot of noise!?
Most probably you hear aliasing. Put a lowpass filter in front of the module and try again. Read more about aliasing on the product page.
There is a way to add pots on the VCSQ! The way to do it is shown here (for more detailed info just email me):
Yes, next to -/+12V the module also needs +5V. The power cable is Doepfer compatible.
On the new TTLFO's there is a red dot of paint on the lower side of the header, this is the -12V pin.
Always check that the red stripe on the powercable is going to -12v at both the module end and the power busboard end. Do not trust the keying on power supply headers, trust the red line and module markings only.
There may be a problem with the ground.
Most probably you put the powercable upside down or you don't have 5V.
If you put the powercable upside down and powered up your modular, unfortunately the TTLFO chip will be burnt in most cases! Always check your powercables before powering up!
But if things went wrong you can always contact me.
