Resumen del manual
The upper frequency limit will be set to a value that is slightly less than half sample rate (frequency). • Adjust the “trigger” threshold. The Threshold can be adjusted to any value from 42 dB to 00 dB below the clip level of the sampler. The default “trigger” threshold is 30 dB below the clip level. If it is desirable to “trigger”, or initiate, the sampling process using either a “Note On” MIDI command or any “MIDI Continuous Controller” command, this can also be accomplished via a separate MIDI System Exclusive command (see the MIDI Supplement). This is helpful when sampling a sound from another keyboard or synthesizer. • Set the maximum sample length. The maximum sample length can be set to any size from “1 word” to the total memory that is installed in the DPM SX. This value can be set in 1 word increments. • While playing the instrument or sound that is to be sampled, adjust the input level control until the clip/threshold LED no longer flashes “red” on the peaks of the signal. As you become more familiar with the DPM SX, you will determine what the optimal signal level is for your own specific needs. Now that all of the parameters are set up, it is time to record your sample. For “manual” sampling, simply transmit a “Start Sampling” message. For “automatic” sampling, send an “Arm Trigger” message and then initiate the sampling process using the predetermined “trigger” method. It should be noted that if the sampling is initiated using the “Start Sampling” message, there might be some slight delay in the actual start due to the delay encountered when the MIDI System Exclusive command is transmitted. This is usually not a problem, since the DPM SX always provides a 512 word “pre-sample buffer.” At this point, the sample resides in the DPM SX sample memory. It can now be transferred to the computer-based sample editor for editing. • To transfer the sample from the DPM SX to the sample editor/player, simply set up the sample editor/player to receive the sample via the MIDI Sample Dump Standard, and request any sample number using the MIDI Sample Dump Request command. The sample will be sent using the number requested. Note: The sample can also be transferred from the DPM SX by pressing the “MIDI DUMP” button on the front panel of the DPM SX. 4.2 Operation with sample editors using the Front Panel If your Sample Editor does not support the transmission of System Exclusive com- 14 mands or it is simply more convenient for you to use the front panel controls on the DPM SX, the following procedure should be used to get the most out of your sampling, • Connect both MIDI cables to the DPM SX and to your computer, allowing MIDI information to be sent in both directions. If you have a complex MIDI system setup, you might want to use a MIDI Data pro-cessor/patcher such as the Peavey MIDI Master to allow for the most flexible MIDI cabling. The Peavey MIDI Master will allow a number of MIDI instruments and controllers to be interconnected in different configurations without having to reconnect the cables each time a new MIDI configuration is needed. • Connect the rest of your MIDI or keyboard system in the way that best suits your needs. • Turn on each unit in your system in the previously described order. • Connect your music or instrument “sound” source to the front panel of the DPM SX. Use the 1/4" phone jack for line level input signals or the XLR jack for any microphone level input signal (phantom powered or otherwise). • Load and start up your favorite sample editing software package. • Select the desired sample rate (depending on the desired sound fidelity or frequency response) by depressing the “SAMPLE RATE” button on the front panel. Using this button, the sample rate can be set to either 24 kHz or 48 kHz, providing bandwidths of either 10 kHz or 20 kHz, respectively. • While playing the instrument or sound that is to be sampled, adjust the input level control until the clip/threshold LED flashes “red” only for an instant on the peaks of the signal. As you become more familiar with the DPM SX, you will determine what the optimal signal level is for your own specific needs. • If the sampling is to be initiated by the input signal, depress the “ARM” button. The LED indicator above the “ARM” button will begin the flash, indicating that the sampler is “armed” and waiting on the input signal to trigger the sampling process. The default trigger level is 30 dB down from the clip level. • If the sample is. to be manually initiated from the front panel, it is not necessary to “arm” the sampler. It is only necessary to depress the “START/STOP” button at the beginning of the sample, and depress it a second time at the end of the sample. If the sample memory is filled before the “START/STOP” button is depressed the second time, the sample process will automatically stop. Note: The sample length (in seconds) will be determined by the sample rate that has been selected and the total amount of mem...
