Hoag Instruments is offering a faster MIDI guitar pickup that is now available for licensing.
Fast response time is the key word here. Magnetic pickups, that started the MIDI guitar evaluation, have given Hoag the challenge of improving the MIDI response time. Other mechanical pickups have been used, but they have difficulty in the lower frequency of the vibrating strings. Response time—the time for the MIDI trigger circuits to latch onto the fundamental of each string—is critical for any MIDI interface. This has been limited by many factors within each pickup. Every trigger circuit relies on the signal fed into it to being the fundamental frequency. If not, it has to filter out the string harmonics. The Hoag Optical Pickup generates the fundamental first, and the harmonics follow.
The first signal that comes from the Hoag Optical Pickup is pure fundamental. For that instant in time the signal has not had time to reach the bridge. It is only after the fundamental reaches the bridge that it has time to create the harmonics and reflect back to the finger position or nut.
Hoag Optical Pickups also greatly expand the frequency of the pickup. The Hoag Optical Pickup is responsive from a few Hertz to well over human hearing.
