Feb 19 2014: Added support for Version C.00 Introduction Thank you very much for purchasing a Logidy EPSi Effect Processor. We hope you find our product an inspiring tool in your quest toward musical bliss. You will find in this document all the information you might need to get the best out of our product. -
Page 4: Presentation
EPSi are not tied to a particular application. Actual parameter names only show on the 3 character LED display and can be changed. And because the firmware running on the pedal is easily replaced via an SD Card, the EPSi can be turned into many different things. -
Page 5: Power Jack
As soon as the EPSi is powered, it will start right away and go through its startup sequence. See the user interface section for more on this. -
Page 6: Sd Card Slot
2.4. SD Card Slot The EPSi uses impulse responses stored on an SD Card. The unit arrived to you with an SD Card pre-loaded with a collection of impulse responses. If, on power- up the EPSi does not detect the presence of a card, a test impulse response generated internally is used instead. -
Page 7: Foot Switch
A single push on the “Param” button causes the display to reveal the name of the current parameter. That name shows as long as the button is pushed and for about 2 seconds after the button is released. After that the display reverts to showing the value for that parameter. -

A peaky or fluttery impulse response form a low quality algorithmic reverb unit will sound the same on the EPSi. However an impulse response from a very diffused and uneven acoustic space will sound as smooth and transparent on the... -
Page 9: Stereo Image Generator
The collection loaded on the SD Card included with the EPSi has impulses from many different high quality sources (acoustic, electronic, electromechanical, and synthesized). The maximum Impulse response duration is about 6 seconds (262144 samples at 44.1 KHz). Only the first 6 seconds of data get loaded for longer duration files. -

Trying to load files that do not match this specification will trigger an error message. 5.2. EPSi “EPDA” Folder The Epsi looks for files in a specific folder on the root directory of the SD Card called “EPDA”. If that folder does not exist, the EPSi reports an error. All files to... -
Page 12: File Naming Convention
The rest of the file name is ignored. Note: If two Wave files have the same 3 digit prefix, the EPSi lists only one of them - picking the one somewhat randomly. -
