System Configuration Example

Roland proposes a DTM system that leverages USB technology. By connecting devices like the SC-88Pro and using sequencing software like Cakewalk, the UA-100 enables recording and playback of audio tracks. MIDI signals can be sent to the SC-88Pro via the UA-100. Mixing audio and MIDI through the UA-100's digital mixer, applying effects, and outputting digitally allows for high-quality master recordings on MD/DAT recorders. The system also enhances home karaoke experiences by connecting microphones to the UA-100 and using the VSC-88 as a sound source.

Benefits of USB for DTM:

• Simplified Connectivity: USB allows connection with a single cable for various peripherals.
• Hot-Plugging: Devices can be connected and disconnected while the computer is running.
• Expandability: USB hubs allow connection of up to 127 devices.
• High-Speed Data Transfer: Enables efficient transfer of large audio and image data.
• Improved Audio Quality: Digital audio output from the computer to the USB device preserves audio quality.

Comparison of Audio Functions:

• Built-in Computer Sound: Prone to noise, resulting in lower sound quality.
• PCI/ISA Slot Sound Cards: Difficult to install, especially in laptops, and requires computer knowledge.
• Roland USB Products: Easy setup with hot-plugging, less susceptible to computer noise, high-quality sound, and compatible with both desktop and laptop computers with USB connectors. Also supports high-volume MIDI data transfer.
