  • Page 2: General Description

    USER MANUAL GENERAL DESCRIPTION Rumble of Ancient Times (RoAT) is an 8-bit noise synthesizer and sequencer, capable of a wide variety of sounds ranging from dense noise scapes to diverse glitching rhythmic patterns. The compact and portable instrument has many features that can be combined into surprising musical results.
  • Page 3 USER MANUAL RUMBLE OF ANCIENT TIMES To configure the synthesizer, you need to change the values of the registers. Each register controls a certain property of the synthesizer, and a total of 32 registers are available. In order to keep the instrument compact and affordable, we decided to divide the settings into pages.
  • Page 4 RUMBLE OF ANCIENT TIMES USER MANUAL SOUND OSCILLATORS Pages 0 and 1 are for tuning the sound oscillators. Pots on page 0 will change the tones of the sound oscillators from 19 to 1,350 Herz. Page 1 will change the waveform of the...

  • Page 5: Low-Frequency Oscillators

    USER MANUAL RUMBLE OF ANCIENT TIMES LOW-FREQUENCY OSCILLATORS LFOs in RoAT are used to control the main oscillators of the synthesizer. They can modulate either the tone of the oscillator or its volume. They are controlled on pages 2,3 and 4.
  • Page 6 RUMBLE OF ANCIENT TIMES USER MANUAL Let's talk more about the last two waveforms. Waveform 7 is a random values generator. If you switch to waveform 6, RoAT will remember the last 8 values and loop them. If you switch back to 7 and 6 again, the looped values will refresh. The same applies to values 14 and 15.
  • Page 7 USER MANUAL RUMBLE OF ANCIENT TIMES ALGORITHMS FOR MIXING CHANNELS Page 6 contains the most important parameters with a high impact on the resulting sound. The pots on this page control how and in what order the oscillator signals are mixed to get the final sound.
  • Page 8 RUMBLE OF ANCIENT TIMES USER MANUAL The picture shows the results of summing two sine waves using different methods. signal 1 signal 2 Addition Multiplication Addition with overflow Exclusive OR (XOR) Subtraction 1 Frequency modulation (FM) Subtraction 2 Waveform modulation As a consequence, there are 8*8*8*3 = 1,536 possible connection patterns for the sound oscillators.

  • Page 9: General Settings Page

    USER MANUAL RUMBLE OF ANCIENT TIMES GENERAL SETTINGS PAGE The last page contains the general settings of the synthesizer and a generator of random changes, or randomizer. The first potentiometer controls the tempo. In RoAT, tempo affects the speed of the LFO and sequencer. The values on the potentiometer are positioned in the following manner: Internal clock.
  • Page 10 RUMBLE OF ANCIENT TIMES USER MANUAL RANDOMIZER There are two systems for introducing random changes to the settings in RoAT. The first system is activated when you press the "Chaos" button. Doing so will randomly change all parameters, except attack, release, system settings on the last page, and the settings on the page currently selected.

  • Page 11: Channel Settings

    RUMBLE OF ANCIENT TIMES CHANNEL SETTINGS Rumble of Ancient Times has 4 channels, but we can switch some of them off to get a desired sound. You can do this in two different ways: Using trigger buttons — Pressing the button will change the state of the channel: if it was OFF, it will switch it ON and vice versa.
  • Page 12 RUMBLE OF ANCIENT TIMES USER MANUAL Each mode has its nuances and range of use. The first mode, bypassing the summing nodes, can be used to make sure the signal continues when one of the channels is switched off. Let's look at an example. Here, the lowest mixing...

  • Page 13: Syncing With Other Devices

    USER MANUAL RUMBLE OF ANCIENT TIMES SEQUENCER The synthesizer has a built-in sequencer that lets you record short looped sections. The length of the recorded section is one 4/4 bar (or 4 clicks of the metronome, or 4 LED signals from the clock).
  • Page 14 RUMBLE OF ANCIENT TIMES USER MANUAL In PO, we need Sync Mode 2. Press and hold Func and BPM at the same time until you see 'SY2' on the screen. That’s it. Press Play and the Pocket Operator will play in the same tempo as Rumble of the Ancient Times.
