Page 4: Introduction
Introduction Fritz is a granular effects device. Incoming audio is sampled and played back in small segments called grains. Many grains can play back at the same time, each with its own snapshot of parameters. This simple mechanism can create complex and p sychedelic effects including pitch shifting, drone synthesis, stutters, glitches, reverbs, pitch smearing, time smearing, chord generation, texture clouds, sonic bursting, and many effects that are too strange to be named.

Page 5: Random Patch Generation
Random Patch Generation Quite possibly the most important button on Fritz is the random patch generator. It is the icon of a die next to the patch loading and saving. Insert Fritz into your effects chain and keep clicking the die to come up with endless permutations of granular effects. Grains Many grains can be active and overlapping at the same time. When a grain is created, its parameters are locked in place. So while there can be constant parameter modulation, a single grain plays back with the snapshot of those parameters from when it was created. Parameter Modulation Modulation Amount Knob. Modulation Source Selection. Almost every parameter can be modulated. Each modulation knob ( ) is shared by the five modulation sources. The active modulation source is selected via the buttons ( ) in the M OD section. The modulation knob will show the active modulation sources’ respective color underneath the knob. The current amount of modulation for each source is shown in the display next to the knob ( ). Stereo Handling Fritz has two separate granular systems running in parallel, one for each stereo channel. Almost all parameter modulation is also in stereo and can be adjusted with L R Phase Stereo c ontrols. Grains can fade over to the other channel using their P an parameter. The S tereo Spread parameter adjusts the output stereo field width. Audio and CV Inputs on the back are normalized to function as mono when only the left is connected. ... -
Page 6: Bypass And Meter Section
Bypass and Meter Section Bypass and Meter Front Panel In B ypass mode, the input signal passes through, unaffected, to the main outputs of the device. In O n mode, the device outputs the processed signal. O ff mode mutes the inputs and outputs. The left stereo meter shows the input signal level. The right stereo meter shows the output signal level. 6 ... -
Page 7: Emit Section
Emit Section Emit Section Front Panel Emit Section Back Panel Rate Sets the frequency at which grains are created. When tempo sync is disabled, the range is from 0Hz (Off) to 500Hz. When tempo sync is enabled, t he available rates are: 32/4, 28/4, 24/4, 20/4, 16/4, 12/4, 8/4, 7/4, 6/4, 5/4, 4/4, 7/8, 3/4, 5/8, 2/4, 7/16, 5/8T, 3/8, 4/8T, 5/16, 1/4, 3/16, 2/8T, 1/8, 1/8T, 1/16, 1/16T, 1/32, 1/32T, 1/64, 1/128. Rate Length Link Enabling the R ate Length Link will cause the L ength of grains to be inversely proportional to the emit R ate . If the emit R ate goes up, the L ength of the grains decreases. If the emit R ate goes down, the grain L ength increases. This helps create a steady number of active grains when the rate fluctuates. ... -
Page 8: Length
Length Sets the duration of the emitted grain. If R ate Length Link is disabled, the L ength range is 0ms to 1sec. If Rate Length Link e nabled, then the L ength range is from 0% to 1000%. When it is set to 100%, the audio will be smooth and continuous as long as all other parameters are at their default state. Link enabled. 200% Link enabled. 100% Link enabled. 50% Link enabled. 25% Noise modulated length 8 ... -
Page 9: Gate
Gate Gate determines whether the emitter is active or not. If G ate is off, no grains will be emitted. Turning the G ate off and then adding modulation can create rhythmic grain emissions. There is an additional CV input on the back for controlling the gate. Jitter Jitter is random noise added to the emitter clock timing. If the emit R ate is set at 10Hz, a grain will be emitted every 100ms. A J itter of 100% would cause each grain’s start to randomly be shifted 0ms to 100ms. J itter does not affect L ength , only emission time. Jitter 0% Jitter 50% ... -

Page 11: Grains Delay Section
Grains Delay Section Grain Delay Section Delay Delay determines the grain playback start position in the input buffer. If tempo sync is disabled, the values range from 10ms to 4sec. If tempo sync is enabled, the a vailable rates are: 4/4, 7/8, 3/4, 5/8, 2/4, 7/16, 5/8T, 3/8, 4/8T, 5/16, 1/4, 3/16, 2/8T, 1/8, 1/8T, 1/16, 1/16T, 1/32, 1/32T, 1/64, 1/128. Scale Scale is a multiplier of the D elay parameter. This can also be thought of as a type of swing/shuffle. Base Delay Scale Final Delay 100ms 50% 50ms 1sec 200% 2sec 1/4 50% 1/8 1/4 125% 5/16 200ms 0% ... -
Page 12: Spray
Spray Spray adds a random amount of time to the delay of each grain. At low values it can cause subtle time smearing of audio, at high values it can create erratic chopping and jumping. The full range of the spray is twice the D elay . So for a D elay of 100ms, the random time added can range from 100ms to +100ms. Spray is applied as an offset after D elay and S cale .

Page 13: Grains Pitch Section
Grains Pitch Section Grain Pitch Section Pitch Probability The P itch Probability strip determines the pitch of a grain. Each box represents a semitone step in pitch shifting, 0 in the middle, +12 semitones at the top, and 12 semitones at the bottom. When a grain is emitted, a pitch offset is selected at random using probability weighting from the strip. 100% +0 Semitones 50% +12 Semitones 33.3% +7 Semitones 50% +5 Semitones 25% +5 Semitones 50% 12 Semitones 33.3% +5 Semitones 50% 5 Semitones 12.5% +2 Semitones 33.3% +0 Semitones 12.5% +0 Semitones 25% 5 Semitones 25% 12 Semitones Examples of Pitch Probabilities for given weights. 13 ... -
Page 14: Reverse
Semitone Semitone adjusts the pitch up to +/ 24 Semitones. This is applied in addition to the P itch Probability . Reverse Reverse is the probability that a grain will play backwards (negative pitch). At 0%, all grains play forward. At 100%, all grains play backwards. At 50% reverse probability, half will play forwards randomly, the other half will play backwards randomly. 14 ... -
Page 15: Grains Envelope Section
Grains Envelope Section Grain Envelope Section Shape Shape determines the amplitude envelope shape of a grain. At a S hape of 0%, the envelope is a cosine curve. At a S hape of 50%, a smooth trapezoid. At a S hape of 100%, a rectangle. The Shape at values 0%, 50%, 100%. Skew Skew will shift the S hape of the envelope in either direction. At 100%, it creates a sharp attack like a ping or pluck sound. At 100%, it creates a reverse sounding grain. Skew values at 100%, 0%, 100% 15 ... -

Page 17: Pan
Pan Fritz has two separate granular systems running in parallel, one for each stereo channel. Grains are always emitted from a single channel’s input buffer. Grains can fade over to the other channel using their P an parameter. At a P an of 0%, grains will remain in their channel. At a P an of 50%, grains will be mixed equally into both channels. At 100%, the grain will be written to the other channel. Modulation of P an will spray the grains across the stereo field.

Page 20: Grains Display
Grains Display The grain display shows each active grain as a dot. Grains in the left channel are blue. Grains in the right channel are red. The grain’s location correspond to its playback position in the input buffer. Each major vertical tick mark represents a multiple of the D elay time. A grain at the 0% bar is playing the input back in realtime, as it comes in. A grain at the 100% bar is playing the input back after the D elay t ime. A grain at the 200% bar is playing the input back after two times the Delay . To see a clear example of this, right click on the Fritz device and issue a ‘Reset Device’ to get everything to its default value. Now, change the grain S cale amount from 0% to 200%, you will see the grains on the display move back and forth from the 0% bar to the 200%, corresponding to the S cale . Now, set S cale to 200% and set ... -
Page 21: Output Section
Output Section Output Section Front Panel Output Section Back Panel Audio signal flows from left to right in the output section. Main Audio Output The main audio output for Fritz. Normalize Grain Levels The number of grains that can be simultaneously played back is variable from 0 to 64, depending on grain Length and emit R ate . Because of this, the output level of Fritz can vary wildly. Enabled by default, Normalize Grain Levels will attenuate grains based on how many are currently playing. This helps to keep the overall volume of Fritz at a useable level. This can be disabled if you wish to control the levels manually or with a limiter/compressor. Insert Effects External effects can be inserted into the signal path. These effects are inserted after the grains are mixed together and before the output diffuser section. See the S ystem Signal Path section. Diffuse Diffuse applies a network of all pass filters to smear the audio in time. This paired with F eedback can create reverb like effects. ... -
Page 22: Feedback
Feedback The amount of signal that is fed back into the input for the grains to resample. Spread Stereo spreading of the output signal. 0% will mix both channels and create a mono output. 200% will invert some stereo signals and create a very wide stereo projection. Dry/Wet Controls the amount of input signal that gets mixed with the effect output. Level Master volume level of the device. Patch Section Patch Section Front Panel Standard Patch loading and saving.
