Le Preamp MIDI configuration
Our Le Preamp Series was designed to be fully integrated into any MIDI environment. The MIDI features of Le Preamp are as follow :
- Le Preamp reacts to and sends MIDI Program Change messages (PC). It does not react to and can't send MIDI Control Change messages (CC).
- Any channel (A, B, Cold or Hot Fusion) of Le Preamp can be activated through one or several PC. It also can be deactivated (bypassed) through one or several PC.
- Selecting any channel (A, B, Cold or Hot Fusion) with the footswiches sends one PC.
- When using several Le Preamps, each Le Preamp can defeat the others, like the channels of an amplifier. This is called the Multi Channel mode, and it does not use MIDI per say, it just uses the same cables. You'll find more information on this here.
Out of the box, Le Preamp is set up with a default MIDI configuration, which is detailled in the user manual. This configuration should address the needs of most users, but if you want something else, you can program Le Preamp through its Setup menu to adapt it to your particular needs. The MIDI programming is detailled in the user manual.
Here are a few situations you may encounter, and how to manage it with MIDI programming. It is assumed that everything is connected with MIDI cables, and the same MIDI channel is selected on each product (or the product is set to recieve all the MIDI channels (OMNI mode)).
1. You have one Le Preamp, one MIDI Torpedo product (or other MIDI device), and you want to assign one preset of the Torpedo to each of the channels of Le Preamp. This is an easy one : activating a channel on Le Preamp will send a PC. This PC is received by the Torpedo, which loads the corresponding preset. The preset # loaded on the Torpedo correspond to the PC # sent by Le Preamp. If you want to load another preset: select the preset you want on the Torpedo, and save it in the slot # that was selected when you activated Le Preamp.
Example: You have Le Crunch with the default configuration. Activating Channel B will send PC #7, and load preset #7 on the Torpedo. If you want to load preset #12 on the Torpedo instead, just select preset #12, and save it on the #7 slot.
Please note this also works with any other MIDI device where you can assign the preset to any #: just note which slot # is selected by Le Preamp, and save the wanted preset in this slot.
2. You have one Le Preamp, one MIDI device, and you want to assign one preset of the FX processor to each of the channels of Le Preamp, but you can't move the presets in the FX processor. In this case, just assign the PC # you need to Le Preamp. This is done through the "PC number" page of the Setup menu. Please refer to the user manual of Le Preamp.
Example: You have Le Bass with the default configuration. Activating Channel Cold Fusion will send PC #18, and load preset #18 on the FX processor (or maybe the FX processor won't load anything because it has less presets than that). If you want to load preset #5 on the FX processor instead: first, note that selecting PC Number x on Le Bass will lead to Cold Fusion sending PC x+2. So, just select PC Number 3 (which is 5-2) in the Setup menu of Le Bass. This leads to Channel A send PC #3, Channel B sending PC #4, and Cold Fusion sending PC #5, which is what you want.
Please note Le Preamp can't send several PC messages at once. Also, channels always send consecutive PC numbers: for example, you can't set le Preamp to send PC #10 on Channel A and PC #15 on Channel B.
3. You have one Le Preamp, one MIDI controler (or any MIDI device sending PC messages), and you want to switch channels on Le Preamp with the controler. As with the two first situations, you can do it two ways. Either program the controler to send the PC # corresponding to the channel of Le Preamp you want (according to the default MIDI configuration). Or use the MIDI Learn page in the Setup menu of Le Preamp: this way, you can assign any PC # to any channel.
Example: You have Le Clean connected to a MIDI controler, and you want to select Channel A on Le Clean when pressing a particular footswitch on the controler. Go into the MIDI Learn page of Le Clean, set Le Clean to Channel A, and press the footswitch on the controler. Le Clean should react by fast flashing of its internal LEDs. Restart Le Clean, and now it should switch to Channel A when pressing the footswitch on the controler.
Please note you can assign several PC# to the same channel, so you can for example switch to Channel A with PC #19, #87 and #127 if you want. You can also assign the bypass of Le Preamp to a PC #.
4. You have several Le Preamps, one MIDI controler (or any MIDI device sending PC messages), and you want to select a channel on one Le Preamp, while putting the other in bypass, with the controler. This is just like the previous situation: just make each Le Preamp react to the PC # you want, the way you want.
Example: You have Le Clean and Le Crunch connected to a MIDI controler, and you want to select Channel A on Le Clean and Bypass on Le Crunch when pressing a particular footswitch on the controler. Go into the MIDI Learn page of Le Clean, set Le Clean to Channel A, and press the footswitch on the controler. Do the same with Le Crunch but in Bypass. Restart both units, and now they should switch to Channel A and Bypass when pressing the footswitch on the controler.
There are probably many other situations where the MIDI functions of Le Preamp can be useful. If you don't find your particular situation described here, please feel free to contact us on the Help Desk for assistance.
