This Grade is CD quality, but has an ingenious compression scheme designed to minimize the space used when the sound is saved to memory. The pad’s default Grade setting is STANDARD.

Choosing the Grade from LONG, STANDARD, or FINE will help determine the final sonic quality of the sample. When saving samples, you will almost always be prompted to choose the Mode, (mono or stereo samples), as well as the sound’s Grade. The point being, you have to use your polyphony wisely, lest you quickly run out. Quickly doing the math reveals that only four stereo samples can sound at the same time. Because a stereo sample is just two mono samples locked together, a stereo sample uses two voices of polyphony. Notice that I said eight mono samples could sound at the same time. But, as soon as the ninth simultaneous sound is played, the very first sound played will be cut off and stop sounding. The samples can be individual hits like percussion sounds, or full-blown loops. That is to say, eight mono samples can sound at the same time. Hey, I just said, “Polyphony!” Simply put, there isn’t a whole lot of it to spare. There are a few things you should know about the SPD-S and its polyphony – polyphony being the number of samples that can sound at the same time. GRADE, MODE, AND THEIR EFFECTS ON POLYPHONY Waveform A waveform is the visual shape of a sampled sound. Threshold The point at which, when crossed, an audio waveform will be recognized by a device. The higher the sample rate, the more accurately the sample will represent the original sound. Sample Rate The number of times per second a snapshot or sample of a sound is taken. Sampling The act of making a digital representation of an analog sound. Resampling The act of saving a sample that has been altered or manipulated as a new sample, leaving the original sample unchanged. The first voice dropped is most often the first voice played. Polyphony The number of voices a synth and/or sampler can play at one time before a voice is dropped. Loops tend to be primarily drums and/or percussion, but may be other instruments, such as guitar. Loop A piece of audio that plays repeatedly end-to-end. Line Level The level of output usually associated with synthesizers, most commonly uses a. The larger the bit depth, the better the sample will resemble the original sound. That said, there are a few basics about sampling and its terminology that will be helpful to know before you power up an SPD-S, and jump into the shallow end of the sampling pool.īit A bit is one single digit of binary code, either a “1” or “0,” “on” or “off.”īit Depth The number of bits used to represent the amplitude of a waveform. Unfortunately, if you want custom sampled sounds and loops, they don’t magically appear perfectly trimmed and ready to use. It even comes loaded with 181 single-strike samples and loops, most of which are very usable. There’s room inside this little box for almost 900 samples. Over 5:30 of internal sampling time, or well over three hours using an external 512MB CompactFlash (CF) card.899 slots for samples (399 internal, 500 on the CompactFlash card).
