USER'S MANUAL (Firmware rev. 1.01 – May 2014) www.GenuineSoundware.com GSi BURN USER'S MANUAL - Pag.
Congratulations on purchasing the GSi BURN, a high quality musical instrument entirely designed and built in Italy. This instrument is the result of years of research and careful study of the effect produced by the famous Leslie rotary speakers. We are confident that the BURN will become an important element of your set-up, bringing big improvements to your sound. We recommend that you read this manual in order to take advantage of all the features that the BURN offers, and store it for future reference.
1. INTRODUCTION GSi BURN is a digital simulator of the "rotary" effect as that of the famous rotary amplifiers from Leslie mod. 122 and 147 and similar, dedicated to electromagnetic organs and their simulators, but can also be used with modern keyboards as well as electric guitars, and is also a versatile multi-effects with MIDI control.
3. CONNECTION PANEL All the connections are on the back side of the BURN. Make sure the unit is turned off before connecting any device. Remember to turn the amplifier on last and always turn them off first in order to prevent damage due to possible electric "bumps". 1. Power switch. Turn the instrument on only when all the connections are completed. 2. Socket for 12 Volt DC power supply. Use only the supplied power adapter. 3. MIDI input.
4. EXAMPLES OF CONNECTION 4.1. Connection of a Workstation keyboard. The BURN offers a stereo audio input on two standard 1/4 inch jacks of type TS (Tip - Sleeve) but the signal used by the processor and by the tube distortion is the left channel for the majority of effects.
5. HOME SCREEN The Home screen shows the preset number, its name, and the values of the following parameters: Tube Gain, Tube Level, Parameter 1 and Parameter 2. This information is updated in real time when changing presets or when MIDI messages are received that require modification. If the tube distortion is on, the symbol of the valve appears between the values GAIN and LEVEL. Rotate the encoder knob to scroll through the 32 presets. NO. PRESET NAME 01: GSi BURN 0 100 100 24 GAIN LEVEL PAR.1 PAR.
9. PRESET PARAMETERS The preset parameters may vary depending on the type of effect in use, for example the ROTARY effects show some parameters that do not appear in other effects. The first page that is displayed by entering the EDIT mode is the choice of the effect. Every time an effect is changed, parameters called Parameter 1, Parameter 2 and Parameter 3 are recalled with their default values according to the current effect.
9.2. OTHER AMPLIFIER SIMULATORS AND MODULATION EFFECTS Effects from no. 12 to no. 23 do not make use of the pedals STOP and SPEED. They activate the Parameter 3 which is controllable through the external accessory connected to the REMOTE jack. # EFFECT NAME PARAM 1 PARAM 2 PARAM 3 DESCRIPTION 12 AMP: VARISPEED Mid. Freq. Reverb Rotary Speed Rotary for guitar with continuous speed control 13 AMP: STACK Mid. Freq. Mid. Gain Reverb Stacked amp for guitar 14 AMP: COMBO Mid. Freq. Mid.
Preset parameters are organized according to the following table: REAL-TIME PARAMETERS VALUE NOTE NON REAL-TIME PARAMETERS VALUE Tube Overdrive Switch On - Off Horn Slow Speed Unplug, Slow, Normal, Fast Tube Overdrive Gain 0 - 127 Horn Fast Speed Unplug, Slow, Normal, Fast Tube Overdrive Level 0 - 127 Bass Slow Speed Unplug, Slow, Normal, Fast Parameter 1 0 - 127 Varies based on the effect Bass Fast Speed Unplug, Slow, Normal, Fast Parameter 2 0 - 127 Varies based on the effect Horn
. RENAME, SAVE OR INITIALIZE A PRESET Each preset can have an alphanumeric name up to a maximum of 12 characters. To assign a name to a preset, go to the [PRESET] NAME page. Press EDIT/ENTER to show the cursor, turn the encoder to position the cursor underneath a character to be changed. Press EDIT/ENTER to change the character. The cursor flashes. Turn the encoder to select the character. To delete a character, turn the encoder clockwise until the character disappears (or appears a space).
12. MIDI SETTINGS The BURN allows a detailed and customizable MIDI control in order to meet multiple needs. It is possible to control all real-time parameters via MIDI, it's possible to recall presets and, most importantly, it's possible to control the Rotary speeds via MIDI commands. The first page of the MIDI settings allows to set the receive MIDI Channel. The range is 1 to 16 or OMNI, that means that incoming events won't take the channel into consideration. Default setting is channel 1.

15. PEDAL SETTINGS The pedals on the BURN can be configured to take different behaviors depending on the user's needs. With the exception of BYPASS pedal, which will always be used to enable or disable the Stereo True Bypass, the STOP and SPEED pedals can also perform other functions. 15.1. BYPASS PEDAL When the True Stereo Bypass is activated, the incoming audio signal found at the input Left and Right jacks is directly led to the output jacks with no change.
16. DISPLAY CONTRAST AND FIRMWARE INFORMATION To adjust the contrast of the LCD display of the BURN according to your preferred viewing angle, go to the page DISPLAY CONTRAST and choose a value between 0 and 64. The default value is 32 and corresponds to an angle of about 80° with respect to the display. DISPLAY CONTRAST VALUE: 32 The next page shows information about the firmware version. FIRMWARE VERSION v1.
18. UTILITY Among the many effect algorithms of the BURN there are two, at the end of the list, considered UTILITY. The first, called PASS THRU, is a digital stereo bypass, it means that the stereo signal coming into the DSP processor is led to the outputs with no change. This could be useful if you want to take advantage of just the tube distortion of the BURN, present only at the left channel, without applying any other effects.
