Product Overview

This collection of Pitch Programs for the Tiptop Audio Z-DSP module use a pitch shifting algorithm

much like the earliest digital pitch shifters released. Sounds similar to the Eventide H910,

AMS 15-80 (with Pitch board) and Publison DHM 89 can be achieved. These programs are

intended more for pure effects rather than the complex multiple harmony lines later devices

and plugins became known for producing. Chords from single VCOs can easily be made using

the ‘Interval’ programs on the card though.

Pitch shifting in the Z-DSP uses a technique called ‘rotating tape head’ delay lines named after

pioneering tape based experiments in Germany in the 1960s. The tape heads move at speeds

independent of the tape playback path and two heads are crossfaded to make a continuous

output. Much of Karlheinz Stockhausen’s output of that era heavily (ab)uses the two tape

machine method of changing pitch. Digital memory and processing allows the same method

by manipulating two playback positions in memory and crossfading them using DSP. This is a

fairly primitive process compared to what can be done today using FFTs (phase vocoder) and

Time Compression and Expansion, but there is a certain sound associated with it that is undeniably

classic.

The first 6 programs all use the same basic algorithm for independent processing of the Left

and Right Inputs on the Z-DSP. The algorithm looks like this:

Left In ---> Pitch Shifter ---> Delay Line ---> Left Output ---> [Analog Feedback to Left In]

Right In ---> Pitch Shifter ---> Delay Line ---> Right Output ---> [Analog Feedback to Right In]

The differences in the programs come from the controls and their ranges to give more access to

certain parameters of the algorithm and make certain effects easier to create.

The delay lines have roughly 500ms of delay on the Left and 250ms on the Right channel. This

gives a nice 2:1 rhythmic effect to the delay.

Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.

If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.

Pre-orders

If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.

If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
