Page 4: Introduction
Tiptop Audio, together with some of the best known programmers in the music industry, are working to bring programs to the Z-DSP platform. The Z-DSP uses an open-source coding environment,... -
Page 5: Getting Started
After a moment, the Z-DSP will load the program found in memory slot 1 on the cartridge. Some cartridges will display a message when first inserted. For example, the... -
Page 6: Signal Flow
Carrier and Signal in a ring modulator. I N S E R T C A R T R I D G E The Z-DSP is truly stereo, no summers allowed! Each channel is built from a distinct audio input , feedback input, processing block, audio output and feedback output. -
Page 7: Analog Feedback
The feedback loop on the Z-DSP is hardwired internally so with nothing plugged into the Feedback Input jack, it is fed from the 100% wet Feedback Output. Turning the Feedback Input knob clockwise will introduce more signal back into the input of the channel. -
Page 8: Digital Feedback
Digital Feedback. Some algorithms process feedback internally, in the digital domain. The texture of digital feedback is much different and brings a very different flavor than analog feedback. Combining analog and digital feedback will bring even more depth to a sound. You’ll know that a program is using digital feedback I N S E R T C A R T R I D G E from FDBK showing on the display as a parameter. -
Page 9: Reading The Panel
Reading the Panel. The Z-DSP front panel contains graphics and typography to help you understand the signal flow and to indicate the functions of the knobs and jacks. Some shortcuts used are: FEDBK or FDBK Feedback VCP1 Voltage control digital Parameter 1... -
Page 10: A Built-In Guitar Preamp
A built-in Guitar Preamp. The Z-DSP contains a simple monophonic Guitar preamp that can be enabled by 2 jumpers at the back of the unit. The first jumper allows a choice between synth (line) level and guitar level. I N S E R T C A R T R I D G E 2&3 = synth level... -
Page 11: Looking Into Voltage Control
Looking into Voltage Control. The Z-DSP contain 2 types of Voltage Control (VC), one is the regular analog control such as the Feedback gain and VC over the Wet/Dry mix. These can be swept at any speed and well into the audio range. - Page 12 Overall the Z-DSP inputs are well protected against excessive voltages on the inputs. We do recommend however to stay within a reasonable range especially in case of using the Z-DSP with modular systems of different format and power supply as the Eurorack standard.

Page 13: Understanding Clocking
Understanding Clocking. Probably one of the most powerful features of the Z-DSP is the CLOCK input. Your computer works by having a processor (CPU) execute lines of program code step by step. The processor runs at a speed that is controlled by a very fast clock. - Page 14 DAC takes the digital data and converts it back to analog form. The programs that run in the Z-DSP work on this digital data, just like you would run a program on your computer to crunch data for your taxes.
- Page 15 At this point the Z3000 is set well above the 20Khz range, which will be our new sampling rate. Now while the Z-DSP is processing a fairly bright sound, plug the Z3000 square wave into the Z-DSP CLOCK input. Congratulations, you just took over the...
- Page 16 Anything is game for the CLOCK input… Modulate the pulse width of your new clock; set it to a narrow pulse so that the detector in the Z-DSP is “hanging on the edge”; try mixing the output of multiple VCOs to create a random clock.

Page 17: Program Switching
The Z-DSP has a built in sequential switch that allows the user to switch programs forward (1.2.3...7.8) or in reverse (8.7...3.2.1) etc. A trigger or gate signal sent to the TRIGGER input will switch to the next higher program (wrapping from 8 to 1). - Page 18 Program Switching. - Continued input the direction will be reversed. To control program switching from an LFO or envelope generator, use the VC-PRG input. A 0-5V voltage swing on this input will switch the program under the same terms as the TRIGGER input. Note that switching time will vary from program to program.
- Page 19 That should be enough to get you started... There's a lot to explore in the Z-DSP, don't be afraid to get funky with it!
