● This is a rare item, the last and highest-end DAW software developed and sold under the YAMAHA name, and is not often found in the used market. ● CD reading confirmed / Installation serial number and instruction manual are included. ● This is a superior, compatible software to XGworks4.0 and XGworksST. It retains the same user-friendly operability as XGworks while enhancing the AUDIO editing features. It is a highly complete software that is still very useful even now, when many of the latest DAW software are available. ● A valuable editor that can control the YAMAHA MU sound source series and PLG onboard series is standard equipment, so it is also highly useful for those who want to fully utilize those hardware. ● The AUDIO operation section is easy to understand, and it is different from the bloated DAW software of today. ● The score editor is well-equipped, so it is also suitable for those who mainly use it for score input and output. ● Xgworks ST is a feature-limited version of SOL2, so you will need this software to use all the features. ● The major difference from SOL (1) is the VST host function, which allows you to use not only the software synthesizers in the package, but also countless commercial and free VST instruments and VST effects (up to 24bit/96kHz, excluding VST3) available. ● The recommended OS from the manufacturer is up to Windows Xp, so using it on 64-bit OS such as Windows 10 or 11 may require some computer knowledge, such as how to install it in compatibility mode within the OS. Please refer to the search results for "How to use YAMAHA SOL2 on Windows 10" etc. for more information. The SOL2 updater is still distributed by YAMAHA, so it is recommended to use it as well. If possible, if you can prepare a Windows Xp or Windows 7 (both 32-bit versions) computer equipped with an RS232 terminal, you can also use hardware sound sources prior to MU128, which is highly convenient. ● As this is an item from an era when copies could be made, returns are not possible. The CD media is in good condition, but the outer box and booklet have some signs of use. This is a personal listing, so we cannot provide a full guarantee. We appreciate your understanding.
