Polivoks synth with FieldScaper app

Polivoks synth with FieldScaper app. Demo of original sound and processed by FieldScaper with several default presets. Synth connected to iPad through 4-pole headphone jack adapter. No external power, no any extra audio interfaces. Only small adapter (white box on video with input level knob).



In this demo FieldScaper uses one oscillator (from three) in loop mode for processing external sound from Polivoks synth. Three default presets were used within this demo.

Two presets configure FieldScaper osc for processing sound directly as it comes from the input. And one preset slices the sound of input loop on small pieces and plays them in random sequences. Which creates the new and very different from source sound.

iPad can give not bad quality of sound even with internal AD/DA for live performance with processing external sound sources like a synth. Very low cost and lightweight solution.

Here is DIY 4-pole headphone jack adapter (you can make it even smaller) and its diagram:

FieldScaper 1.5 has been released!

FieldScaper ver. 1.5 with full screen field recorder for iPhone in landscape orientation and improved support for control via MIDI has been released.


What's new in this update:

  • Full screen recorder / sample editor for iPhone landscape.
  • Supported Dropbox service for download and upload files.
  • Improved Inter-App Audio support as Musical Instrument and Effect.
  • Supported Inter-App Audio MIDI connection, BPM and transport controls.
  • List of assignable MIDI controls divided by categories.
  • Direct, Pick-up and Scaling modes for faders with MIDI controller.
  • Sending states of buttons and faders for display state on MIDI controller.
  • Improved automatic start for mode "Loop A" in the looper.
  • Improved user interface for built-in description.
  • Updated description of the application.
  • Several minor bugs have been fixed.

FieldScaper has different user interface for iPhone / iPad in portrait and landscape orientation. In portrait orientation the screen is divided between Recorder and Oscillator controls. You can easily record new sample and immediately load and process it in the oscillator.

For more convenient use of this application as field recorder on iPhone just rotate it to landscape orientation. This transforms the user interface into full screen recorder without oscillator. This mode is very useful for recording and editing samples on iPhone.

On iPad in landscape orientation on the screen placed the Recorder and controls for all three Oscillators. This mode is suitable for recording and operating with samples when you use FieldScaper in real-time as instrument with all three oscillators, especially with MIDI controllers.

In addition you can switch the user interface to the mode of Looper. This mode is specially designed for use FieldScaper as real-time effect processor and looper. All controls are made so that you can quickly change presets and samples, use the main controls for oscillators and select the mode for processing the input signal.

FieldScaper live improvisation with MIDI controller

In this demo FieldScaper app on iPad is used as main audio processing unit and fully operated by using external MIDI controller.


What were used in this setup


Two synthesizers (one with additional effect unit) were used as external audio sources for first oscillator in FieldScaper. This oscillator was configured in mode "Looper" - "Effect". Synthesizers were connected to two different input channels of external audio interface in mono mode. In the app these channels combined to one for use in oscillator. For this oscillator was used the slightly modified preset "Dark and foreboding places".

With this preset (as well as others) you can discover a whole new aspects of already familiar sounds and presets of synths. In other demo you can hear how this preset can transform sounding of usual synthesizer pad -

Two other oscillators (second and third) were configured for using preloaded samples with several presets. All oscillators were operated by using MIDI controller. The six faders at the right side are assigned on "Main effect" and "Output level" for each oscillator. Buttons below assigned for switch between presets and samples. Knobs at the left side are assigned for mixer "Distance" / "Panorama", filter "Frequency" / "Resonance" and for "Clock" / "Clock offset".

MIDI controller and external audio interface are connected to iPad (in this demo iPad 4 with iOS 9.3.1) thru Lightning to USB camera adapter and usual USB hub. If the controller or audio interface require a power thru USB you need use USB hub with external power adapter.

FieldScaper can fully operated by using external MIDI controller. With advanced MIDI controller you can access many parameters of the app in real time. But even with simple controller you can change basic parameters of oscillators (such as "Main effect" and "Output level") and easily switch between presets and samples. This very conveniently at live performance.

Also FieldScaper has special mode "Looper" in which on the single screen are placed several main controls for oscillators and buttons for quick switching between presets and samples. This mode is specially designed for comfortable use this app for live performance even without external MIDI controllers.

Glitched ambient (FieldScaper app in Looper mode)

This demo shows one way to use the mode "Looper" - "Overdub" in FieldScaper app for real-time processing and transform sound of the input source.


How to make something like this

In the mode "Overdub" recorder will start record into loop when the input signal becomes above threshold and stop when below. But playback of the loop don't stop and already recorded signal not erased. So you can continuously update the loop by overdubbing only part of its content. It can be very creatively when you use presets that changing the pitch, direction and addressing (see Oscillator - Address section) when playback.

To get the result something like this demo you need switch to the mode "Looper" (button "Looper" on the main screen) and select processing mode "Overdub". Then assign one of preset buttons to factory default preset "Dark and foreboding places" and set this preset active. Set the fader "Effect" to about the half right.

In the panel of input settings (button "Input" or "Audio input control") set the parameter "Stop recording threshold" to about -15 db. To avoid the large silence gap in the loop set the parameter "Stop recording time" to about 0.100 sec. This will reduce the tail with low volume level between the input signal drops below threshold and record will stopped.

Also it's recommended to increase parameter "Input amplify" up to about +10 db so that the level of input signal was at least from -15 db and more even with a small limiting. Many presets give the best result when the input signal level is high enough.

When the input source is synth or other musical instrument or app set the input channel filter at least from "40 Hz" to "12 kHz" ("16 kHz"). When record from microphone the best use "60 Hz" filter to avoid unnecessary peaks that can affect to the signal threshold detector and gate.

After complete all settings tap the button "Start" (in the mode "Looper") to start processing the input source.

Move the fader "Effect" to get other sound. You can change any other parameters of this preset to achieve another effect and then create your own preset. Start from "Filter - Frequency / Resonance" and its LFO and also try to change "Oscillator - Clock / Clock offset".

Upcoming FieldScaper 1.4 will have looper mode

New version FieldScaper 1.4 will have new advanced looper mode for convenient use this application in real-time sound mangling.

FieldScaper - an advanced field recorder combined with a sound warp engine and a collection of ready to use dynamic presets for iPad and iPhone. Discover new ways to create and construct unusual and exciting sounds from any environmental audio recordings or samples recorded from other apps through Inter-App audio or Audiobus.


The "Looper" mode changes the user interface to more convenient use of application in real-time and processing external sources. Use the button "Looper" on the main screen to switch on this mode. For return to the main screen use the button "Scaper".

In this mode you can fast switch the presets and samples for each of oscillators. For oscillator there are five assignable buttons for presets and samples. First oscillator can be fast selected for processing of any external sound sources (include IAA and AB) in one of four modes.

Please note: In the "Looper" mode application does not create any files when processing external sources.

The four buttons are selecting the processing mode for external source.

"Effect" - In this mode the input signal will record to the loop and oscillator is playing back this loop at the same time. The speed and direction of playback can differ from recording depending on current preset.

"Overdub" - In this mode the record to the loop will be enabled when the input signal exceed specified threshold. When input signal falls below another threshold the record will be off but already recorded signal will continue playing back. The recording can be started and stopped at any time in the loop.

Tip: To shorten the time of stopping record when input signal falls below threshold you can set a lower value of "Stop recording time" on the "Audio input control" panel.

"Loop A" - This mode intended for auto start the record at the beginning of the loop when input signal exceed specified threshold. Next the oscillator will playing back this loop.

"Loop M" - Mode for manual start recording to the loop. The led on the "Start" button will flashing when waiting for record start. Tap the "Start" button to switch on the mode of waiting input signal. When input signal appears the record will start and stop at the end of loop.

When you select the "Loop M" mode you can use input monitor when the "Looper" waiting for start (The led marker on the button "Start" is flashing). Set the "Input monitor - on" mode to get source signal on the output at waiting for start. After start the input monitor will mute.

"Input" - This button opens the "Audio input control" panel. In this panel you can set the thresholds of input signal for start and stop recording.

Above the control buttons is placed the area in which the loop record is displayed. Two moving markers point the record and playback position in the loop. Bright bars indicate when the minimum of signal is present (above -35 db). Red bars mark the optimal level of signal for processing in the scaper (above -10 db).

The five buttons below the control buttons can be assigned for selecting presets and samples.

"Assign preset" - Assign preset for one of five buttons above.

"Assign file" - Assign file for one of five buttons above.

You can assign MIDI controls for the preset and file select buttons and for looper "Start" button. All of these controls are at the end of list which accessible on the panel "Settings" - "Assign".

electronic MUSICIAN - April 2016 - Synth Apps Virtual Instruments for iOS Musicians

This month we check out Synth Apps, virtual instruments for iOS musicians.

The Electronic Musician Guide to iOS Soft Synths – In recent years, using iOS-based synthesizers onstage and in the studio has become a practical reality. One reason is that the latest iPads and iPhones contain more powerful processors than even some recent laptop computers. Apps are growing considerably more sophisticated and more closely resemble their computer-based equivalents, often by leveraging all that processing power. Thanks to economies of scale and the difficulty of pirating iOS apps, they’re also less expensive (and often more versatile) than synthesizer hardware.
