SquareSynth Manual

SquareSynth is a table-based synthesizer for iOS. Using the “tables” you can create sounds similar to 8bit game consoles, and computers. It is modeled after the NES/Famicom. Use the preset patches to get started!!

First thing to notice is the envelope. This is a common way to control the amplitude of a synth. Here is an explanation of ADSR Envelopes. Pulse Width is a common synthesizer setting. The PulseWidth knob goes from 0 to 1 (approximately). The position will make the sound of a Pulse wave “fatter” or “thinner.” This knob and the wave buttons are disabled when the Table is on.

This is where you can change the Pitch, Waveform type, or Pulse Width over time. This is the “Power House” of SquareSynth. You can study the presets to see how to make various types of instruments. Percussive instruments are usually very fast (high Speed setting), and contain different “stages.” For example, most kick drums are formed with a clicky sound, and/or a punchy sound (fast downward pitch slope), and a deep tonal sound. When you play these sounds very fast, you get a kick drum. There are many possibilities. For some tips check out the Table Instrument Guide.

Wave Recorder:


In version 1.5 the recorder behavior was modified. In order to record using the new version, hit record, then hit play, or a piano key. This allows you to record single notes at the very beginning of the record sample. This type of sample is called a “one-shot.” It also lets you wait until a sequence of notes has begun to start recording. In genreral, it’s a good way to align your exported samples.

When you tap the Export button in the Record view, two things happen; the audio is copied to the clipboard, and shared with iTunes.


How the clipboard works is that SquareSynth copies a stereo wav file on to the clipboard. You then would go into another app and paste it, but there’s a caveat; not all apps support audio paste. When another app tries to use the data on the clipboard, it looks at the type of the data on the clipboard. If it recognizes the type as something it knows how to use, it will do so. Otherwise it will just do nothing.

So, to copy wav data from SquareSynth to another app, using the clipboard, you first tap the Export button in the Record view.

Now you switch to another app that knows how to use wav data from the clipboard. Here’s two lists of apps which support it:



These apps will have an Audio Paste option for you to use (consult the manuals). The clipboard will hold your audio until you copy something else.

File Sharing

The other thing that happens when you hit the Export button is a wav gets shared with iTunes (for your Mac/PC). To access this file:

Connect your iDevice to your Mac/PC.

Go to the “Apps” section

Locate the File Sharing area at the bottom of the page.

Locate SquareSynth in the list of File Sharing apps, and click it.

You will see your file in SquareSynth Documents list. Drag it to your desktop, or use the Save To… button.


Midi CC Inputs:

Each of the first four midi channels is routed to a different patch. Configure them on the PREFS->MIDI DEVICE screen.
