Issues

Reported but not confirmed crashes

  • Crash when quicksaving a CPU-heavy (or memory-heavy?) patch (50+ units).

Confirmed crashes

  • None at the moment

Bugs

  • 6-track Recorder > Save Recording dialog in 6-track recorder does not show files when saving a single track.
  • Slicing View > Not possible to revert slice edits.
  • Any Player with shift > bugs in shift parameter, only works in slicing mode
  • Crash when opening quicksaves and patch contains 50+ units.
  • Grain Stretch > grain rendering is not respecting slice boundaries.
  • After X hours, sample playback glitches (reported but not confirmed on my end yet but seems to be power supply related).
  • Discontinuous playback when playing unit shares buffer with another recording unit (play/record head leapfrog bug).
  • Sample Player wave display sometimes does not reflect newly recorded content of a shared buffer. (see Forum: Question about looper/recorders and sample players with shared buffers)
  • Standardize zoom buttons everywhere.
  • Local routing > Feed-forward paths that connect a source higher in the chain hierarchy with destinations lower in the hierarchy will have one frame of delay.

Cosmetic bugs

  • scope traces draw outside of border
  • frequency display on gate/trig parameters sporadically shows incorrect value
  • short triggers do not show up on the bicolor LEDs (frame rate aliasing)
  • Mono subchains of stereo chains do not show signals on scope if 2nd channel is selected.

Feature Requests

Tip-bulb.png
The majority of the requests listed here were compiled from requests made by users over at the forum.
Pitfall.png
Please do not purchase the ER-301 only because of something(s) on this list because there is a risk that I might not get all of these features implemented in a time-frame that is useful to you. I will work hard (but not to the point where I destroy my health or my love for modular) and hopefully the upcoming SDK will alleviate some of this time risk but it is still a very real possibility that some of the items on this list will never be realized.

Middle Layer

  • View cycling assumes only two views. Allow for more.

Custom Units

  • Promote/demote controls on embedded units to the parent custom unit.
  • Hide controls that are used for implementation only. Differentiation between UI and implementation.

Unit Parameters

  • user bookmarking of specific values for quick selection of often used values (via shift+encoder)
  • parameter recall via stack semantics (push and pop)
  • combine L/R faders and use channel select buttons to determine L vs R vs LR

UI enhancements

  • AIFF support
  • remap Gx and INx when loading a chain preset into a different channel
  • Clearly display buffer/sample assignment in units that have them.
  • Tween GUI animations against wall clock instead of frame clock
  • Give me a list of everything that is connected to source X!
  • Add note display to any unit with a V/oct + f0 controls.
  • Custom/MultiBand > The sub-display is empty for the bands/patch.
  • Setting > Auto-purge unused saved samples from pool when running out of sample memory.
  • Put back unit re-init command.

Scopes

  • tuning info
  • adjustable time and amplitude scales

Firmware updating

  • implement restore points (copies of files that were changed by the firmware update)
  • add scripts to be executed before and after the installation

Presets

  • shareable packaging
  • projects that contain quicksaves and paramsets.

Slicing

  • Slicing View > Slice on Loudness.
  • Sample Slicer > No way to remove loop points without deleting slice.
  • Global slicing vs local slicing.
  • many slice files for one audio file
  • many audio files for one slice file
  • learn function for slice selection
  • support for WAV cue chunks (see thread)
  • JSON/XML formatted files

File browser

  • ops: rename, delete, move
  • package preset for sharing

Looping

  • layering looper (see thread)
  • variable speed recording
  • pedal Looper > double loop length
  • speed control
  • more monitoring options
  • reverse
  • half speed
  • loop volume level
  • option to begin overdubbing immediately after first record pass.

Sampling

  • Clocked Players > allow use of derived clock for sync.
  • Playlist Player (or add list to Card Player)
  • enhance Card Player to support negative speeds
  • Ping-Pong on gate Hi
  • Better support for clickless playback of shared buffers that are being recorded.
  • next slice trigger
  • more slice types (bounce, jump, random)
  • specializations
    • sampled instrument player (i.e. keymapped ADSR samples, sfz files)
    • drum kit player (i.e. multiple one-shots in parallel)
  • Offer to purge unused samples when sample memory is full. (see thread)
  • end of slice trigger (see thread)
  • end of slice fade
  • play to end of sample even in sliced mode (see thread)

Mixer(s)

  • add/remove channels
  • specialize mixer into 3 types: insertion, layering, song (see forum post)

Clocking and Timing

  • snap and recall tempo for Tap Tempo

EQ3

Delay(s)

  • freeze/reverse via gate input
  • spectral delay

Oscillators

  • more waveforms
  • sinc-based pulse-trains

Utilities

  • Grid Quantizer > add ceiling and nearest rounding modes.

  • Exponential VCA
  • VCA+Envelope quick combo

Filters

  • more peaks (or specialized formant filter?)
  • add resonant band pass
  • Exact Convolution > Add "Edit Sample" to menu.

Lookup Table (LUT)

Wavetables

  • basically looper optimized for very short loops with pitch/loudness normalization

  • (user-assisted) pitch normalization of each wavetable/loop
  • (user-assisted) loudness normalization of each wavetable/loop
  • morph between multiple wavetables/loops
  • phase modulation
  • offset modulation

Unit templates

  • user saves the state of a unit as a special preset that will be used whenever instantiating the unit

Settings

  • button bounce time
  • default delay max time
  • default fade time
  • flash message time
  • zoom step for wave displays
  • common default parameter values (mixer gain, VCA level, etc.)

Command and Event Bus

  • command messages broadcast or sent to specific units
  • example of command response: clear buffer to all loopers
  • example of event generation: End-of-Cycle
  • command generation unit that will emit a set of commands when a trigger is received
  • events are efficient (i.e. frame-rate) triggers?

Teletype Integration

  • add SC.PRESET command to load quicksaves
