1. 5 volts Size 3 units 14 hp www gotharman dk2. the pitch tracking will be slower and more smooth It is also possible to modulate this control using any CV source Connection example 1 Connect a microphone to input 1 through a microphone amplifier or any playback device playing back a voice sampling Connect the output of an oscillator to input 2 Put all controls in the middle position Connect the PitchShaper output so it will be audible Now when you speak in the microphone or plays back the voice recording you will hear the waveform coming out of the oscillator being re pitched to match the pitch of the voice Experiment by turning the controls and changing the pitch and shape of the oscillator Connection example 2 Try the opposite of example 1 Connect the output of the oscillator to input 1 and the microphone voice recording to input 2 When you speak in the microphone or plays back the voice recording you will now hear the voice re pitched to match the pitch of the oscillator If changing the pitch of the oscillator the voice pitch will be changed but the voice speed will remain Experiment especially with the Sense 2 control since this will be the main source for creating granular effects in this set up Specs Analogue to digital conversion 24 bit Digital to analogue conversion 24 bit Internal sound system 24 bit 44 1 KHz Power requirements and 12 volts Power consumption 130 mA Accepted control voltages Up to 10 volts Recommended
3. Sotharmans Pitchshaper Eurorack Module LJAer Manual Introduction Dear valued GotharMusic customer Thank you very much for purchasing a PitchShaper eurorack module The PitchShaper are a new Gotharman invention made because of a wish of being able to pitch match any sound to a voice before it was going into a vocoder for making a more realisticly pitched vocoder voice When working on the design as usual found that there could be many more uses for such a module By adding just a few controls it really became possible to shape the sound output from this module into something completely different than just a pitch matched signal And by switching the 2 inputs around it became possible to re pitch the voice itself without changing the speed of the voice and by turning the controls creating strange granular effects By adding beats and other sound sources to it the fun really began The PitchShaper are a digital module based on a 24 bit 44 1 KHz highend audio system to ensure a smooth and warm sound that fits into a highend analogue modular system sincerely hope that you will enjoy playing with your PitchShaper as much as have enjoyed designing it Gotharman April 2011 Installation The PitchShaper should be mounted in a eurorack modular system and will require 14 hp of space It will also require a power supply of 12 V 130 mA Start by mounting the 16 cored grey or multi coloured flat cable that cam
4. e with the module One end of the cable should be mounted on the 16 pin connector on the back of the module Make sure that the red line on this cable are pointing towards the text on the printed circuit board saying 12V If your module came with a multi coluored cable it will be the brown line Mount the other end of the cable to your eurorack power distribution board Make sure that the red or brown line of the cable will be connected to 12 V here too Mount the module faceplate with screws Functionality The PitchShaper analyses the pitch of the audio signal applied to input 1 and then re pitches the audio signal applied to input 2 to match the pitches The audio signal present on the audio output will be the signal of input 2 re pitched to match pitch of the signal applied to input 1 That is the main functionality of the pitch shaper Since this module is created using granular technology by adjusting the controls it is possible to obtain a very broad range of granular effects Even though it has rather few controls they all has a broad range and interact with each other thus giving a very broad range of sounds Audio In 1 and 2 Adjusts the input level of the 2 connected sound sources These 2 controls should be adjusted in conjunction with Sense 1 and 2 to obtain the wanted result Sense 1 This control adjusts the pitch tracking sensitivity of audio input 1 and should be adjusted in conjunction with the Audi
5. o In 1 control in order to obtain the wanted effect If this control is turned fully counter clock wise it will be very sensitive and migth even pitch track to the background noise If turned fully clockwise it will not be sensitive at all and will not pitch track to the input signal Start out by putting this in a middle position and experiment to find the setting that suits the best It is also possible to modulate this control using any CV source Sense 2 This control adjusts the pitch tracking sensitivity of audio input 2 and should be adjusted in conjunction with the Audio In 2 control in order to obtain the wanted effect While Audio In 1 is the controlling pitch this control adjusts how sensitive it will be in matching the pitch If this is turned fully counter clock wise it will be very sensitive and it will match smaller fragments of the signal appled to input 2 to the pitch of the signal applied to input 1 higher pitch When turning this control up it will be less sensitive making the fragments bigger and the pitch lower When turned fully clock wise it will not track at all just playing back what was last stored in it s buffer This is useful for creating granular effects It is also possible to modulate this control using any CV source Smooth This control adjusts how smooth the pitch tracking should be When turned fully counter clock wise the pitch tracking will be extremely fast When turned fully clock wise
